MList is a program which allows you to create and manage mailinglists. In addition it is possible to allow website visitors to subscribe and unsubscribe lists.

In the MList webinterface you can choose which HTML result documents are assigned to the /cgi-f/subscribe and /cgi-f/unsubscribe tools.

The HTML-Subscribe-Return-Page will be displayed after succesfull list signup.
The HTML-Unsubscribe-Return-Page will be displayed after unsubscribing.
If there are errors during the subscribe/unsubscribe process, the HTML-Subscribe-Error-Page or HTML-Unsubscribe-Error-Page will be displayed. Errors will occur if an users tries to subscribe with an email address which is already in the list or if someone tries to unsubscribe an address which is not in the list.

In addition you can choose a notification email address where subscribe and unsubscribe processes are reported.

MList could be completely controlled by email as well. The email gateway allows to subscribe, unsubscribe and publish. To activate the email gateway for a mailinglist you have to create an alias from the list "listname" to the target "mlist".



To subscribe to a list, users simply send an email to
listname@mydomain.com with the word "subscribe" in the subject line. Of course, you have to replace the actual name of the list and "mydomain.com" with your own domainname.
Unsubscribing works similar by sending a mail to listname@mydomain.com with the word "unsubscribe" in the subject line.
If the subject is not "subscribe" or "unsubscribe" the mail will be send to all members of the list, given that the sender is a member of the list as well.

In the MList webinterface you can choose the texts used for the email gateway.

In addition to the webinterface the /cgi-f/subscribe and /cgi-f/unsubscribe tools are part of MList as well.

With this form users can subscribe to the mailing list list:

---

<FORM METHOD=POST ACTION="/cgi-f/subscribe?l=list">
<INPUT TYPE=text NAME=a VALUE="">
<INPUT TYPE=submit VALUE="Subscribe">
</FORM>


---

Here is the corresponding HTML code for unsubscribing:

---

<FORM METHOD=POST ACTION="/cgi-f/unsubscribe?l=list">
<INPUT TYPE=text NAME=a VALUE="">
<INPUT TYPE=submit VALUE="Unubscribe">
</FORM>


---

If a text is published to MList list members, you can enable the receiver to unsubscribe. MList replaces the word MLISTRECEIVER with the actual email address of the receiver. A text like

To unsubscribe, visit this page
http://mydomain.com/cgi-f/unsubscribe?l=liste&a=MLISTRECEIVER

will be converted to

To unsubscribe, visit this page
http://mydomain.com/cgi-f/unsubscribe?l=liste&a=peter@aol.com

Of course, you have to replace the actual name of the list and "mydomain.com" with your own domainname.
