Do you know off hand if > amavis can handle the SQL prefs, or do I need to keep things as they are? i think it can, but i don't use it myself (i use my own little filter script) so i'm not 100% sure. the advantage of using an MDA is that you get greater per-user customisation capability because by the time it gets to the MDA, the final recipient address is known and that can be used as a lookup key into the SQL prefs. this information isn't available earlier than that (although you can fake it by using the recipient address...which mostly works but has a few problems, e.g. with catch-all addresses or aliases, each one would need it's own custom config even though they end up in the same mailbox. this may be a feature or it may be a bug depending on what you want :-) OTOH, using spamassassin from an MDA only works for mail delivered to the local system. it does not work for in-transit mail (e.g. relayed, uucp, etc). if you need that, use SA as a content filter. like i said, there are pros and cons to both. craig -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I'm currently calling spamassassin (spamd) via procmail after piping through amavis, because I want to use SQL prefs. Do you know off hand if amavis can handle the SQL prefs, or do I need to keep things as they are?

So, if I understand correctly, I *have to* enable SpamAssassin through an MDA? I thought SpamAssassin could be called by amavisd-new, which would make the MDA unnecessary, since Postfix can deliver to Maildir directly.. Regards, -- R.M.
