I need to implement a Mailman list on my LAN so users can subscribe to lists via email notification:

http://www.gnu.org/software/mailman/index.html

My question is rather simple but I don't know if this can be easily accomplished.

My email server (Postfix) simply runs just mail applications:

- Postfix
- Dovecot
- Amavisd-new
- Clamav
- Spamassassin

Now in order to install Mailman, you must have Apache running so this means I can NOT install Mailman on my email server. I am allowed to install Mailman on my web server which is on the same physical LAN / subnet as my email server:

mail - 192.168.0.100
web1 - 192.168.0.101

Is it possible to install Mailman on my web server & have it function accordingly to my mail server which re-sides on a completely separate server as my mail server? I would assume this to be a common installation process but could not find any info on this...

I don't know much about mailman, but you could set up a separate email server on your web server box and use that only for mailing lists. Otherwise, look into something other than mailman.

I'll bet mailman wants the web server for configuration, so maybe you could configure a way to make the web server copy configuration data on to your mail server. Ultimately, probably not a good idea.
