CGI Mailform, ik snap er helemaal niets meer van

Beste allemaal, Sinds een tijdje werkt mijn contact-formpje niet meer op mijn site. Ik liet hem voorheen via een andere site lopen, maar ik denk dat die er mee gestopt is. Ik heb diverse sites gevonden waar ik de benodigde materialen kan downloaden om dit script zelf te installeren, maar ik krijg het maar niet voor elkaar. Ik blijf gekke meldingen krijgen.

Misschien dat één van jullie mij even zou willen en kunnen helpen?
Alvast heel erg bedankt!!!


Je server ondersteunt toevallig geen php?

Je server ondersteunt toevallig geen cgi-scripts? :)

... de server wel, maar ik zelf niet zo. Ik heb helemaal geen verstand van PHP. Helaas.... CGI snap ik iets meer van, ik krijg het alleen niet voor elkaar in CGI

kun je dat script hier plaatsen?

het is een hele lap tekst, maar hierbij het CGI-Script:

List of files



There are a number of variables that you can change in which
alter the way that the program works.



This should be set to 1 whilst you are installing
and testing the script. Once the script is live you
should change it to 0. When set to 1, errors will
be output to the browser. This is a security risk and
should not be used when the script is live.

=item $emulate_matts_code

When this variable is set to a true value (e.g. 1)
formmail will work in exactly the same way as its
counterpart at Matt’s Script Archive. If it is set
to a false value (e.g. 0) then more advanced features
are switched on. We do not recommend changing this
variable to 1, as the resulting drop in security
may leave your formmail open to use as a SPAM relay.

=item $secure

When this variable is set to a true value (e.g. 1)
many additional security features are turned on. We
do not recommend changing this variable to 0, as the
resulting drop in security may leave your formmail
open to use as a SPAM relay.

=item $allow_empty_ref

Some web proxies and office firewalls may strip
certain headers from the HTTP request that is sent
by a browser. Among these is the HTTP_REFERER that
the program uses as an additional check of the
requests validity - this will cause the program to
fail with a ‘bad referer’ message even though the
configuration seems fine. In these cases setting
this variable to 1 will stop the program from
complaining about requests where no referer header
was sent while leaving the rest of the security
features intact.

=item $max_recipients

The maximum number of e-mail addresses that any single
form should be allowed to send copies of the e-mail to.
If none of your forms send e-mail to more than one
recipient, then we recommend that you improve the
security of FormMail by reducing this value to 1.
Setting this variable to 0 removes all limits on the
number of recipients of each e-mail.

=item $mailprog

The system command that the script should invoke to
send an outgoing email. This should be the full path
to a program that will read a message from STDIN and
determine the list of message recipients from the
message headers. Any switches that the program
requires should be provided here. Your hosting
provider or system administrator should be able to
tell you what to set this variable to.

A $mailprog setting that works for many UNIX-like
hosts is:

$mailprog = ‘/usr/lib/sendmail -oi -t’;

Some other UNIX-like hosts need:

$mailprog = ‘/usr/sbin/sendmail -oi -t’;

For hosts that lack a suitable sendmail binary (such
as most Windows systems) we have a Perl script which
does the job of the sendmail binary, in the nms_sendmail
package at E<lt><gt>.
See the README file in the nms_sendmail package for

=item @referers

A list of referring hosts. This should be a list of
the names or IP addresses of all the systems that
will host HTML forms that refer to this formmail
script. Only these hosts will be allowed to use the
formmail script. This is needed to prevent others
from hijacking your formmail script for their own use
by linking to it from their own HTML forms.

=item @allow_mail_to

A list of the email addresses that formmail can send
email to. The elements of this list can be either
simple email addresses (like ‘you@your.domain’) or
domain names (like ‘your.domain’). If it’s a domain
name then any address at the domain will be allowed.

Example: to allow mail to be sent to ‘you@your.domain’
or any address at the host ‘mail.your.domain’, you
would set:

C<@allow_mail_to = qw(you@your.domain mail.your.domain);>

=item @recipients

A list of Perl regular expression patterns that
determine who the script will allow mail to be sent
to in addition to those set in @allow_mail_to. This is
present only for compatibility with the original
formmail script. We strongly advise against having
anything in @recipients as it’s easy to make a mistake
with the regular expression syntax and turn your
formmail into an open SPAM relay.

There is an implicit $ at the end of the regular
expression, but you need to include the ^ if you want
it anchored at the start. Note also that since ‘.’ is
a regular expression metacharacter, you’ll need to
escape it before using it in domain names.

If that last paragraph makes no sense to you then
please don’t put anything in @recipients, stick to
using the less error prone @allow_mail_to.

=item %recipient_alias

A hash for predefining a list of recipients in the script,
and then choosing between them using the recipient form
field, while keeping all the email addresses out of the
HTML so that they don’t get collected by address
harvesters and sent junk email.

For example, suppose you have three forms on your site,
and you want each to submit to a different email address
and you want to keep the addresses hidden. You might
set up C<%recipient_alias> like this:

%recipient_alias = (
‘1’ => ‘one@your.domain’,
‘2’ => ‘two@your.domain’,
‘3’ => ‘three@your.domain’,

In the HTML form that should submit to the recipient
‘two@your.domain’, you would then set the recipient with:

<input type=“hidden” name=“recipient” value=“2” />

=item $locale

This determines the language that is used in the date - by
default this is blank and the language will probably be
english. The following a list of some possible values,
however it should be stressed that not all of these will
be supported on all systems and also this is not a complete

=item $charset

The character set to use for output documents.

=item @valid_ENV

A list of all the environment variables that you want
to be able to include in the email. See L<env_report|/item_env_report>

=item $date_fmt

The format that the date will be displayed in. This
is a string that contains a number of different ‘tags’.
Each tag consists of a % character followed by a letter.
Each tag represents one way of displaying a particular
part of the date or time. Here are some common tags:

%Y - four digit year (2002)
%y - two digit year (02)
%m - month of the year (01 to 12)
%b - short month name (Jan to Dec)
%B - long month name (January to December)
%d - day of the month (01 to 31)
%a - short day name (Sun to Sat)
%A - long day name (Sunday to Saturday)
%H - hour in 24 hour clock (00 to 23)
%I - hour in 12 hour clock (01 to 12)
%p - AM or PM
%M - minutes (00 to 59)
%S - seconds (00 to 59)
%Z - the name of the local timezone

=item $style

This is the URL of a CSS stylesheet which will be
used for script generated messages. This should
probably be the same as the one that you use for all
the other pages. This should be a local absolute URI
fragment. Set $style to ‘0’ or the empty string if
you do not want to use style sheets.

=item $send_confirmation_mail

If this flag is set to 1 then an additional email
will be sent to the person who submitted the

B<CAUTION:> with this feature turned on it’s
possible for someone to put someone else’s email
address in the form and submit it 5000 times,
causing this script to send a flood of email to a
third party. This third party is likely to blame
you for the email flood attack.

=item $confirmation_text

The header and body of the confirmation email
sent to the person who submits the form, if the
$send_confirmation_mail flag is set. We use a
Perl ‘here document’ to allow us to configure it
as a single block of text in the script. In the
example below, everything between the lines

$confirmation_text = <<‘END_OF_CONFIRMATION’;



is treated as part of the email. Everything
before the first blank line is taken as part of
the email header, and everything after the first
blank line is the body of the email.

$confirmation_text = &lt;&lt;'END_OF_CONFIRMATION';

Subject: form submission

Thankyou for your form submission.




Formmail is installed simply by copying the file into your
cgi-bin directory. If you don’t know where your cgi-bin directory is, then
please ask your system administrator.

You may need to rename to FormMail.cgi. Again, your system
administrator will know if this is the case.

You will probably need to turn on execute permissions to the file. You can
do this by running the command “chmod +x” from your command
line. If you don’t have command line access to your web server then there
will probably be an equivalent function in your file transfer program.

To make use of it, you need to write an HTML form that refers to the
FormMail script. Here’s an example which will send mail to the address
‘feedback@your.domain’ when someone submits the form:

<form method=“post” action=“http://your.domain/cgi-bin/”>
<input type=“hidden” name=“recipient” value=“feedback@your.domain” />
<input type=“text” name=“feedback” /><br />
Please enter your comments<br />
<input type=“submit” />


See how the hidden ‘recipient’ input in the example above told formmail who
to send the mail to? This is how almost all of formmail’s configuration
works. Here’s the full list of things you can set with hidden form inputs:


=item recipient

The email address to which the form submission
should be sent. If you would like it copied to
more than one recipient then you can separate
multiple email addresses with commas, for

<input type=“hidden” name=“recipient”
value=“you@your.domain,me@your.domain” />

If you leave the ‘recipient’ field out of the
form, formmail will send to the first address
listed in the @allow_mail_to configuration
variable (see above). This allows you to avoid
putting your email address in the form, which
might be desirable if you’re concerned about
address harvesters collecting it and sending
you SPAM. This feature is disabled if the
emulate_matts_code configuration variable is
set to 0.

=item subject

The subject line for the email. For example:

<input type=“hidden” name=“subject”
value=“From the feedback form” />

=item redirect

If this value is present it should be a URL, and
the user will be redirected there after a
successful form submission. For example:

<input type=“hidden” name=“redirect”
value=“http://www.your.domain/foo.html” />

If you don’t specify a redirect URL then instead
of redirecting formmail will generate a success
page telling the user that their submission was

=item bgcolor

The background color for the success page.

=item background

The URL of the background image for the success

=item text_color

The text color for the success page.

=item link_color

The link color for the success page.

=item vlink_color

The vlink color for the success page.

=item alink_color

The alink color for the success page.

=item title

The title for the success page.

=item return_link_url

The target URL for a link at the end of the
success page. This is normally used to provide
a link from the success page back to your main
page or back to the page with the form on. For

<input type=“hidden” name=“return_link_url”
value="/home.html" />

=item return_link_title

The label for the return link. For example:

<input type=“hidden” name=“return_link_title”
value=“Back to my home page” />

=item sort

This sets the order in which the submitted form
inputs will appear in the email and on the
success page. It can be the string ‘alphabetic’
for alphabetic order, or the string “order:”
followed by a comma separated list of the input
names, for example:

<input type=“hidden” name=“sort”

=item print_config

This is mainly used for debugging, and if set it
causes formmail to include a dump of the
specified configuration settings in the email.

For example:

<input type=“hidden” name=“print_config”

… will include whatever values you set for
title’ and ‘sort’ (if any) in the email.

=item required

This is a list of fields that the user must fill
in before they submit the form. If they leave
any of these fields blank then they will be sent
back to the form to try again. For example:

<input type=“hidden” name=“required”

=item missing_fields_redirect

If this is set, it must be a URL, and the user
will be redirected there if any of the fields
listed in ‘required’ are left blank. Use this if
you want finer control over the the error that
the user sees if they miss out a field.

=item env_report

This is a list of the CGI environment variables
that should be included in the email. This is
useful for recording things like the IP address
of the user in the email. Any environment
variables that you want to use in ‘env_report’ in
any of your forms will need to be in the
valid_ENV configuration variable described

=item print_blank_fields

If this is set then fields that the user left
blank will be included in the email. Normally,
blank fields are suppressed to save space.


As well as all these hidden inputs, there are a couple of non-hidden
inputs which get special treatment:


=item email

If one of the things you’re asking the user to fill in is their
email address and you call that input ‘email’, formmail will use
it as the address part of the sender’s email address in the

=item realname

If one of the things you’re asking the user to fill in is their
full name and you call that input ‘realname’, formmail will use
it as the name part of the sender’s email address in the email.




=item confusion over the qw operator

In the configuration section at the top of FormMail, we set
the default list of allowed referers with this line of code:

@referers = qw( localhost);

This use of the C<qw()> operator is one way to write lists of
strings in Perl. Another way is like this:

@referers = (‘’,‘’,‘localhost’);

We prefer the first version because it allows use to leave out
the quote character, but the second version is perfectly valid
and works exactly the same as the C<qw()> version. You should
use whichever version you feel most comfortable with. Neither
is better or worse than the other.

What you must not do is try to mix the two, and end up with
something like:

@referers = qw(‘’,‘’,‘localhost’);

This will not work, and you will see unexpected behavior. In
the case of C<@referers>, the script will always display a
“bad referer” error page.

=item sendmail switches removed

In the configuration section at the top of FormMail, we set
the default mail program to sendmail with this code:

$mailprog = ‘/usr/lib/sendmail -oi -t’;

This is actually two different pieces of information; the
location of the sendmail binary (F</usr/lib/sendmail>) and
the command line switches that must be passed to it in order
for it to read the list of message recipients from the
message header (C<-oi -t>).

If your hosting provider or system administrator tells you that
sendmail is F</usr/sbin/sendmail> on your system, then you must
change the C<$mailprog> line to:

$mailprog = ‘/usr/sbin/sendmail -oi -t’;

and not:

$mailprog = ‘/usr/sbin/sendmail’;

Alvast bedankt, Michael

Dat is inderdaad een hele lap tekst, weet je zeker dat er op je server sendmail is geinstalleerd en dat het pad klopt? (/usr/sbin/sendmail)

Dutchwebhosting, de hoster van de site, biedt dit formmailscript zelf aan, dus ik denk het wel, al durf ik het niet met zekerheid te zeggen... Maakt het niet makkelijker he?! hahaha Bedankt alvast! Michael

Volgens mij heeft het script niet de benodigde rechten. Ik weet niet uit mijn hoofd welke dat moeten zijn, ik zal even zoeken.

De rechten van het script moet: 755 zijn, en dat is: owner: alle rechten group: read en execute (geen write) everyone: read en execute (geen write) Weet je hoe je rechten kan zetten? Als de host het script zelf aanbiedt zal het script wel in orde zijn, mag je aannemen... Dingen om op te letten: het pad naar de sendmail moet goed staan in het script, soms moeten er 'hidden fields' in de html-form worden gedefinieerd.

en welke foutmeldingen krijg je?

Ik krijg op dit moment alleen maar 'internal server error'. De rechten heb ik op de juiste manier toegekend. Dat was nog simpel. Maar ik heb hier 6 prints liggen met hoe je het script zou moeten configureren. Zover als ik weet heb ik dat gedaan. maar inderdaad het pad naar de sendmail is denk ik het probleem... de hidden fields zijn allemaal goed ingevoerd...

Iedereen in iedergeval bedankt voor het helpen… ik ga nog even verder zoeken…


Een internal error kan o.a. een script met te veel rechten als oorzaak hebben, b.v. 777.

Andere oorzaak kan zijn dat het script alleen uit te voeren is in bijvoorbeeld de cgi-bin map.
