1.) I think of switching some of my users from pop3 to imap ... Matthias you wrote about courier-imap ...
My questions: - any experience with imap on qmail?
No. Supposedly works, and I don't see reasons why it would break. However, I use those on Postfix which is a lot faster, and I switched to courier-imap's pop3d to have it use exactly the same authentication schemes.
- do I have to switch the whole thing to imap, or can I run pop3 and imap parallel?
You can have both of them.
- what's about security with imap? (ok ... I know pop3 does not have any either)
Courier-IMAP offers STARTTLS and SSL-wrapped service, just configure it and you're set (you may need to install OpenSSL 0.9.6b before installing Courier-IMAP).
- are there different distributions of imap servers? (which one fits into qmail with vchkpw)
Yes, try Google to fing about courier-imap + vchkpw.
2.) Another theme is about virus scanners in mailer daemons. I've read an article about virus scanners which can be implemented directly into the postfix system ...
Any experience with virus scanners for qmail?
Some are just filtering SMTP proxies that work everywhere, some are file filters, search the MTA's mailing list archives.
