After looking at this somewhat and cranking up the logging, it APPEARS
that what happens is that I have marked
youroptinmail.com DISCARD
in the access database. Whenever we get an email from risquemail.com,
which is served through a youroptinmail.com mail server I get a series
of log messages that look more or less like this:
Jul 31 05:32:23 eric.servers.uwrf.edu sm-mta[24207]:

It appears that it is the access entry that is making milter-greylist fail.
I'm finding that we really can't use milter-greylist in production
because of this - it crashes some times several times in an hour.
Is it just impossible to blacklist anything in access and use
milter-greylist as well?
Also - I have tried a few times to set up milter-greylist so that I can
whitelist in the Access database as well- but I cannot get that to
work. The docs really don't explain very well how to do this. And if
you really follow the instructions as written, it will break your other
milters because if you really set the macro entries explicitly to just
the macros that milter -greylist needs, then it removes the default
macros that your other milters needed. Okay, so I figured that out, but
I still cannot tell what I am supposed to put into an access entry to
actually be able to whitelist something for milter-greylist.
I eventually took the macross for access out of the m4 sendmail config,
since I was afraid that was what was making milter-greylist crash, but
that seems not to help.
This is the second greylisting milter I've tried that doesn't seem
stable in production - milter-gris was much worse, crashing any time
there was any particular load on the server. Greylisting really seems to
make a huge difference in our spam levels, but I can't seem to find a
stable implementation to use.
