I have a server with RedHat 7.2. It has sendmail running, currently just forwarding all email to other addresses. I am running several different domains on the server.

What I want to do is the following:

1) Be able to set up email accounts (POP I guess) so that different users can get their email for different domains.

2) Preferably so that the admin for a particular domain can administrate email addresses e.g. set up new accounts for that domain, set-up forwards etc.

3) Have all of the above in a nice, easy to configure and install package, which is robust and secure.

Does such a thing exist? I have spent a while with Google but can't find anything suitable. I thought setting up email accounts on my server would be easy, but it's proving to be difficult!

Many thanks.

I would suggest using qmail for smtp and pop then use webmin for account creation/maintainace.
