[Dovecot] Replacing qmail + vpopmail with: sendmail + dovecot
Hi, I wonder if it posible to replace qmail + vpopmail with sendmail + dovecot?
The idea is like this:
- use sendmail + milter API to filter spam/virus and deliver the email to the dovevot MDA (LDA)
- dovecot should save the email to the directory as specified in the vpopmail DB
- maintain the vpopmail BD (users + passwd)
- use dovecot pop3/imap for the clients
- use sendmail again to receive the email from the pop3/imap users and deliver the email to the internet as usual.
Anyone has done this? It is posible in the paper, in the real world?
many thanks Oliver

Sure, anything is possible, but if you are trying to get away from qmail+vpopmail, you should probably move to postfix instead of sendmail (unless you /like/ pain ;). Sendmail is a monolithic monstrosity that is barely able to be managed by mortals. Postfix is designed (like qmail and vpopmail), as a series of small programs that do one thing and do it well. There should be a FAQ entry for switching to Postfix virtual users from vpopmail; check the Postfix site...

+1 from me.
Postfix is really user-friendly and it also comes with very good documentation including many examples.

I was going to recommend Exim instead of Sendmail. Exim is in my opinion the best.
Hi Jhon, the problem is that I need to code the company policies in perl, and that I can only do using sendmail + milter API + mimedefang.
Also, I'm migrating a user DB that is in vpopmail.
Thanks Oliver

postfix does support the sendmail milter API, as well as other content filtering methods

I believe something like PostfixAdmin should have a similar DB layout to what you already have, which should make migration fairly easy
Theres a good setup guide in the Dovecot wiki -

Mi Mick, many thanks for the tips.
I'm asked suppor about mimedefang in postfix and get zero answer, so I will put sendmail as relay in front of postfix and postfix will be running on localhost at port 26 or something.
Thanks Oliver
