= Postfix/Notes_on_converting_a_customer_to_virtual_mailboxes =

From work, notes made for an enquiry regarding wave50

----

== postfixadmin ==
 * postfixadsmin requires virtual mailboxes
 * means migrating to virtual mailboxes
 * virtual mailboxes are centrally owned
 * need to restructure into `/domain/user`
 * virtual mailboxes means virtual delivery
 * could maybe stay as mbox, will still need to point to other "folders"
 * need to normalise all addresses (will take a few hours at least)

== postfix lookups ==
 * postfix needs to back onto the DB
 * can shape the queries a little bit, but not that much
 * don't have to use Deliver, but it's good

== dovecot ==
 * dovecot has to use the DB for mail location now
 * dovecot shares that DB for auth now
 * this affects SASL
 * everyone's SASL credentials may have to change

== implementation thoughts ==
 * convert to LDA (postfix -> dovecot -> LDA delivery)
 * this would shift out of system users
 * need to normalise all addresses first
 * difference between passwd file and SQL should be pretty small
 * could use imapsync to move all the mail?

== time estimates ==
 * address normalisation - 3hrs
 * mbox to maildir conversion - 3hrs (some 540MiB of mail)
 * planning time so far - 2hrs
 * documentation - 2hrs
 * setup postfixadmin - 0.75hrs
 * populate the DB backend - 2hrs
 * configure postfix - 0.75hrs
 * configure dovecot - 1hrs
 * testing - 2hrs
 * pricing - 0.5hrs
