unique pop3 users for multiple virtual hosts
sendmail configurations

 5:49 pm on Dec 9, 2001 (gmt 0)

I have just transitioned to a dedicated server, and have been trying to figure out how to configure sendmail for multiple domains. I'd like to be able to set up multiple pop3 mailboxes for each domain (many are managed by different people), and have the problem of conflicting usernames:

I've figured out how to route each of these addresses to a different user on the system like webmaster-d1 and webmaster-d2, but I've seen shared hosts before where the pop3 login is webmaster@domain1.com which does not seem to be a valid username on linux. How is that done? Anyone have an idea or a resource they could point me to.

I can't answer your question ggrot, sorry. But I can "bump" your post so it gets more attention, and I can bring it up in the mods forum. Perhaps one of our resident wizards will have some suggestions.

Sendmail can't be used as a POP3 or as an IMAP server, it is basically a mail relay. You will need something else to act as a POP or IMAP server which can support actual login by a mail client. Sendamil uses SMTP to transfer messages between servers, but SMTP requires amother protocol such as POP3 to collect and process messages locally and deliver messages to specific users. Most Linux distributions come with IMAP servers, you'll want to configure it for user access, being careful about the options you choose, mail servers are notorious security risks when improperly configured.

You may find THIS [linuxgazette.com] useful, hope it helps.

Cool timing, I've been putting off setting up a IMAP server. I was actually using a combination of smtp and sendmail relay to get and send mail for my virtuals. It's a pain to do it that way, but IMAP seemed intimidating. It isn't really, it was a lot easier than configuring sendmail to do what I want.

I followed the instructions on that link (it's a little dated like a lot of howtos) and the IMAP readme. I got it running in about 30 minutes. Thanks.
