off to the
Sent Items instead of leaving it in the Outbox.
I'm running Debian Sid on my SMTP server, and it's got Courier 0.68.2-1,
which suggests that 0.64.0 is rather out of date, and there might have
been a bug in it which caused it to both pass back the 450 error
as the 2nd line of defense, but it rarely gets called upon to
declare an email as spam.
Greylisting works because of two things:
1) The SMTP protocol requires SMTP servers to re-try delivery to a
remote server if they are given a soft error code;
and will see 0 spam email get in for
months on end.
Also, when you say that your email address is given in all-caps, are
you refering to the RCPT TO: in the SMTP transaction of the 'To:'
field in the DATA of the SMTP transaction?

As per a previous message from you, you are using a MySQL backend.

Incoming mail would be handled over SMTP, most probably, so Postfix

You aren't by any chance using greylisting via pythonfilter?
If so, check the version of the db files it uses with the `file` command.
Best way to check to see if it MIGHT be greylisting DB issues is to

I am assuming that your email server has multiple network connections
and the attacks are coming from the external interface, not the internal
one.
That way, you don't have ANY impact on your 17,000

1 Spammer was persistent enough to get around the greylisting but, as
previously posted, has been caught out by SA.
All in all, I'd say greylisting is a true winner for anyone wanting to
