I understand thats not squirrelmails problem. What I noticed is that when a new system user attempts to log via squirrelmail the following message is returned:
ERROR: Connection dropped by IMAP server.
This last until the user receive his first mail, i.e. when maildir is created by the system.
I know I can type:
Maildir for that user will be created, but Im not aiming to create Maildir for each user one by one. The other problem is that after creating Maildir this way, messages to the user cannot be delivered, as shown bellow:
This is the mail system at host mail2.ustm.ac.mz.
The mail system
<firstname.lastname@example.org>: maildir delivery failed: create maildir file
