I have Julian Fitzell's migrateuser.sh script which uses mb2md-3.20.pl to convert a mailbox in mbox format to Maildir. I have set up a test user called "mailtest" which has mail as follows: /var/mail/mailtest /home/mailtest/mail/ Drafts MoreStuff Sent Items Stuff After the conversion I want all this user's mail to be in /home/mailtest/Maildir/ I'm not quite sure how to run the migrateuser.sh script, but I think it's like this (run as user mailtest): $ /usr/local/bin/mb2md/migrateuser.sh mailtest /home/mailtest /home/mailtest/Maildir When I run this I get the following output: mailtest -- Migrating INBOX... Converting /var/mail/mailtest to maildir: /home/mailtest/Maildir.mdwork.1237291760 Source Mbox is /var/mail/mailtest Target Maildir is /home/mailtest/Maildir.mdwork.1237291760 Created UID list: /home/mailtest/Maildir.mdwork.1237291760/dovecot-uidlist 3 messages. warning: Can't open /home/mailtest/Maildir.mdwork.1237291760: not a selectable mailbox [ERROR] (mismatch during post compare) mailtest -- 0 new message(s) (), 3 total mailtest -- That bit about "not a selectable mailbox" seems to be the problem. Any idea what I'm doing wrong here? Regards, Phill
