Im curious if anyone is archiving emails and what they are using. I currently utilize sendmail/procmail/dovecot.
What exactly do you mean by archiving?
We use Postfix and Dovecot to backup any sent and received mail for our users. Postfix, using sender_bcc_maps, resends any mail to the sending user via an address extension (i.e. mail sent by foo@example.org gets resent to foo+sent@example.org) and Dovecot with Sieve, using the sieve_before directive, filters such sent mail into a private namespace that is hidden from the user (Backup/sent).
Backing up received mail works very similar (ending up in Backup/received) but Postfix is not involved; this is a job for Sieve alone, again using the sieve_before directive and an appropriate script.
So Postfix/Dovecot/Sieve. If ACLs worked a bit better in 1.2.x [1] I could even make the Backup namespace visible to its user and just ensure, via ACLs, that the user cannot delete any messages in this namespace. But this'll have to wait for 2.0 I believe.
Does that answer your question?
