I am using PHP to make a medium, which looks like a mailing list. What it should do is the following:

It should be controlled by an e-mail address. The e-mail server is running PostFix + QPOP.

When sb. send an e-mail to mail@mydomain.nl, it should
1. be forwarded to other addresses
2. be saved in a MySQL-database.

If you ask me, it looks like a mailing list, but it should be controlled by e-mail. Do I have to config the mailservers, or is it just possible to use PHP.

oh, I almost forgot: I have NO ACCESS to the crontab, and I don't like to use a cronjob to do this job. Is it possible to do in another way?
