This means the SMTP agent (sendmail?  You don't seem to say anything
about which MTA you're using, although I've been shockingly adept
as missing such hints lately) refused the delivery for that
user; the -1 is the "smtp_code" (or rather the lack of one) from
smtplib.py; the 'ignore' is the "smtp_error" (or lack of one)
from smtplib.py.  See SMTPDirect.py's deliver() method for where
those things are set and accumulated in the refused dict.

Looks like the transaction was really unsuccessful, as in "couldn't
open a socket to the SMTP port at all".

Maybe; could be a digest post, for which 177 are failing.  How
many digest members are there?  (bin/list_members -d <list> | wc -l)

That definitely means that you couldn't open a connection to the SMTP
port, for whatever reason.  Is your MTA going up and down?  JC's
question about "what does your MTA say" is a good one.

Also, running qrunner by hand and watching what it does, either by
sniffing network traffic on port 25 or system-call-tracing, would be
illuminating, I'm sure.

They both mean the same thing: that many more bounces will be allowed over
that time period before the user is considered for bounce removal
action (which might be "disable", or "notify", or "remove".  Mostly
normal; there are always lots of bounces.

This means you have a Python that supports threads, correct?
I have no experience with such a setup.  I split them into chunks
with a patch to SMTPDirect.py which I hope to get Barry to look at
soon, authored by someone on one of these lists whose name I have
lost...SMTP_CHUNKIFY is a good unique string to look for it.

This all sounds a lot more like MTA issues than Mailman; I'd focus
debug efforts there.
