Archiving mail on IMAP server
Version 1.4 of MailArchiveByDate now supports archiving to IMAP folders.
It works exactly as expected for me, but some users have reported problems with the script not creating new mailboxes. If the mailbox exists, the messages are moved. I have not been able to reproduce the problem myself using dovecot on Fedora Core 4 or Scalix (which is supposed to look like an Exchange server).
