Mar 25 10:16:45 server6 mimedefang[12794]: i2PGDuDQ012793: Bouncing because filter instructed us to
Your filter has called action_bounce. This is normal.
Mar 25 10:16:45 server6 mimedefang[12794]: i2PGDuDQ012793: set_reply returned MI_FAILURE
Not sure, but I think it means something is preventing MD from setting the response message for the SMTP rejection.
Mar 25 10:16:45 server6 sm-mta[12793]: i2PGDuDQ012793: Milter: data, reject=554 5.7.1 Command rejected
Milter has told sendmail to reject the message with the code "554 5.7.1 Command rejected". Except for the code, this is normal. I'd guess that milter fell back to a default response when MD failed to set a specific one.
Mar 25 10:16:45 server6 sm-mta[12793]: i2PGDuDQ012793: to=<[EMAIL PROTECTED]>, delay=00:00:06, pri=35693, stat=Command rejected
Sendmail is doing what your filter told it to and rejecting the message. This is also normal.
The key problem is in the second line, with the MI_FAILURE.
So you've got two issues:
(1) Why is some mail being rejected? It's supposed to be! Look for action_bounce in your filter to figure out how it's deciding this and change it if necessary.
(2) Why is it using a generic message instead of something informative? That's harder to tell. Make sure action_bounce is being called with valid parameters. Something as simple as action_bounce("I don't like this mail") is fine - see the man page for mimedefang_filter for more options. If that looks correct, maybe there's a problem with your milter installation? Did you upgrade sendmail without rebuilding mimedefang? Did you install MD from a binary RPM built against a different version of sendmail? At this point I'm just guessing.
