Greetings all,
After migrating a few dozen people to our departmental mailserver, we've run into a problem with one user who makes extensive use of folders and nesting them. I've seen as many as 8 levels. The longest resulting folder name is 113 characters, which results in a total path length of 137 characters (/var/spool/mail/******).
mbox or maildir? What OS? What filesystem?
Their old mail server handled this fine, but dovecot is choking on it; imapsync reports "invalid mailbox name", and he gets the same error clicking on the mailboxes in Thunderbird (they seem to have been created, despite the error messages.)
Try talking IMAP protocol directly:
1 login user pass 2 create mailbox/name
Are you sure it's because of the mailbox name length? Maybe there's something else wrong in the name?
The hardcoded mailbox length is 512 characters. With Maildir++ it's typically 255 characters because of OS/filesystem limits.
