Yes, this can be done. But if you're using UNIX system user accounts IIRC you'll have to convert to virtual users before you can migrate one user at a time. Virtual user setup is required to change mail_location on a per user basis. With system users mail_location is defined once for all users. Converting to virtual users first makes the process more painful. I've not done such a POP mbox<>maildir migration myself, so hopefully someone who has will chime in. If not start a new thread called "need POP mbox<>maildir migration help" or similar. And again, I wouldn't try any of this with 1.0.7. Upgrade to at least 1.2.x first. >> Always test with a dummy mailbox first to iron out any issues.

State your version, current user account type (system or virtual), and post your dovecot -n at the end of the email. You'll get many more helpful suggestions and insight from people who've actually done this migration. -- Stan
