Migrating email

Migrating from unix /var/mail/spool mail to maildir:

Moving from a old Verio VPS server to Softlayer’s cloud required migrating from the old “unix” email format where all mail for a user was kept in a single file.
Softlayer/WHM offered two email formats, courier or dovecot. I had luck with dovecot and did not pursue courier.

as root:
copy old mail file to /var/spool/mail/user_name

make sure permissions are user_name / mail

as user_name, from /home/user_name/mail/domain.com
mb2md.pl -m -d /home/user_name/mail/domain-com/mail_user

mail is now in dovecot format and readable via POP/IMAP or webmail (:2092/:2093 or webmail.domain.com)

repeat for all needed accounts

consider running “/etc/init.d/postfix stop’ on the old server

on softlayer/centos6/LAMP, yum install perl-TimeDate was required for mb2md.pl to ‘compile’.
