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/******).
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.)
Mail was imported over using imapsync, and did so flawlessly for all the other accounts.
Are we running up against a soft (configuration file) or hard (source) limit? Or is this a bug?
Thanks! Brett
