The mail server is finished, although I suspect I’ll be tweaking it for a while yet. Final setup is postfix / postgrey / amavisd-new / spamassassin / clamav / cyrus / horde, all using OpenLDAP authentication over TLS with saslauthd for Cyrus and Postfix.I had been using procmail in between postfix and cyrus, but that prevented Sieve from working, so I have removed it from the chain.
Tweaking Horde (with Imp, Ingo, Turba, Nag, Kronolith, Mnemo, Dimp, Mimp, Gollem, Passwd, etc) has been time-consuming – especially getting Passwd to change the OpenLDAP and Samba passwords, thus making it a single point of password change for the new network.
Now migrating mail from the old ClarkConnect server to the new one, should be finally swinging over this week…
