Virtual mail domain and POP problem

Question

Hi all,
I am currently on my 7th or 8th install of 10.5 server, so far without managing to make a working mailsetup with virtual domains and virtual users. That is, it works when my customers use an IMAP-client (or webmail via squirrelmail), but it doesn't work when using a POP-client. I have yet to discover the cause of my problems, as the server-logs show perfectly good logins – but unfortunately nothing gets downloaded to the client.
I currently host 15 domains, which until my purchase of 10.5 server were hosted on a computer running 10.4 client-version with dovecot as mailserver, a custom DNS-setup and various custominstalled supporting apps. On the old client, everything was running smoothly (albeit slowly, due to the old hardware), but as I have stated, on my new server I can't get POP-access to work.
When I do a fresh install of 10.5 server, I can log in to the accounts on the primary domain with either POP3 or IMAP, but as soon as I set up a virtual domain, POP-access to all accounts ceases to function.
I suspect Cyrus configuration to be the main culprit, since everything else seems to work as expected, but having no previous experience with cyrus, I have yet to find a solution.
If anyone has any pointers to a good source of cyrus-IMAP knowledge, I would be very grateful for any help.

Hi Alex,
This is really strange, and it's also really bugging me!
I use OD. If I add several shortnames to a user, fqn and not-fqn, I can only log in with the first shortname and any of the fqn-names. However, only the login using the first shortname recieves any mail.
I dont know if you have any explanation as to why my setup doesn't include a /etc/postfix/virtual file or a virtualaliasmaps statement in main.cf, which is the only difference in my system that I registered compared to your guide.
This is some lines from mailaccess.log when logging in to an account using Outlook Express in XP (user info masked):

The log level is set to "Information", and as you can see all logins appear to be successful. However, only the first login using the comexampleuser login receives any mail (and I sent more mails inbetween to make sure something would register, of course).
Here's the relevant part from mail.log:

And here are the output of ps U _cyrus when logging in via POP (I have removed the IMAP-lines, as I doubt they are necessary, but feel free to correct me if I'm mistaken).

I hope some of the above will provide some clues.
