OK. I am sure it's obvious, but I cant see it.
Any suggestions would be appreciated.

I am trying to consolidate several email servers. The goal is to have pop mail and webmail access to several email domains that I want vhost on a single server.

I have an existing properly functioning postfix/cyrus/spamassassin config running on suse 10.3 64bit and I have successfully setup all the vhosts and I am able to send/rec via pop/smtp (e.g. outlook) to/from all vhosts. I installed squirrlemail on the same server and made the suggested changes as per the squirrelmail doc to the postfix config (e.g. Maildir and owners/permissions). The existing postfix mail continues to function properly and is now utilzing the Maildir format mail files. I am also able to access the squirrelmail app and log into it and send mail, but the squirrelmail isnt using the maildirs as configured in postfix. I believe the issue is that squirrelmail or cyrus isnt config'd properly, but damed if I can figure it out.

Here are the relevant config snippets.

partition-default: /var/spool/imap
sievedir: /var/lib/sieve
