Hi,

I am trying to work out how to setup an email server with the following features.. (No I am not an ISP I just think that an ISP type mailserver would be the best answer.)

1. SMTP / POP3 / IMAP + SMTP TLS / POP3s / IMAP4s would be nice..
2. POP before SMTP or SMTP Auth for roaming users..
3. Per user configurable (can be increased or decreased) mailbox quota's..
4. Virtual users stored in MySQL DB (I don't want system accounts for each mailbox..
5. Webmail
6. Scaleability ( I want to be able to partition the system later if needed eg 1 or more servers for inbound SMTP, 1 or more servers for outbound SMTP and 1 or more servers for POP3/IMAP..

Starting with the MTA, I think Postfix is the best choice since it natively supports virtual users in a MySQL DB.. Onto that I was going to use Courier-IMAP which also supports user information in a MySQL DB.. but here is the problem..

Courier-IMAP only supports the maildir format.. While Postfix supports Maildir it does not support mailbox quota's on Maildir based mailboxes.. This is a problem.. There are alternate POP3/IMAP servers but they are not able to use a MySQL DB as the backend..

Also I think the theory of Maildir sounds good so I would rather use Maildir instead of the Mailbox format..

Sorry if I am getting a little technical on the requirements I would like to have..

What mail server software do the ISP's on this forum use because I am sure I am missing something here?? There must be an easy way to do this..

BTW, cost is an issue so the system needs to be free or fairly cheap..

Later..
