Hi Nicola,

Thank you for your reply.

There are no error messages in the log (local6.debug
-> /var/log/local6.log) when the user logs in:

Oct 15 09:19:49 nixlizard imap[79721]: inittls: Loading hard-coded DH parameters

Thunderbird says "Mailbox does not exist".

I get more detail when I try imapsync(1):

[...]

After your reply, I turned on autocreate_post:

autocreate_post: 1

However, messages sent to the user bounce. When I create the mailbox
manually, the message is delivered.

I have no virtdomains turned on, and:

unixhierarchysep: no

cyradm listmailbox \* lists only mailboxes I have created manually.

What else should I look into?
