I'd seen docs in the postfix distro showing a content filter running on one socket submitting back to a different socket that Postix is listening, on. I guess that's a reasonable way, thanks for the recommendation. What about the lmtp -> dspam -> lmtp -> cyrus scenario, do you have any experience? It just seems a little cleaner to me for no apparent reason.
I have dspam 3.8.0 daemon with a MySQL 5 backend as a content filter between two Postfix 2.5.1 smtpd listeners and it has worked well for many months (like years, with updates). dspam cannot resend lmtp, it uses smtp. I don't use Cyrus for IMAP etc., I use Courier; Postfix hands off via pipe to maildrop.
smtpd on 10025 -> dspam lmtp on 24 -> smtpd on 10026. I use an inet socket rather than Unix to dspam.
