These seldom went over a few hundred per list per week, so it didn't actually take all that long. kind of a fri or mon morning-over-coffee task that I always suspected could be automated, but in-the-end, was a thing that really was best handled by someone who cared about 'delivering the mail' !

Also, if you are testing greylisting from a GMail account, GMail tends to retry messages from another random outgoing server, so it may take considerable time before GMail happens to randomly pick an outgoing server it has already used and greylisting can confirm the same message from the same user at the same server...

If the GMail address used to send is the same as the address subscribed to the test list, you won't see it because GMail deduplicates aggressively. There is no way to fix this in GMail. If you are testing from GMail you *must* use a separate address as the recipient. Check the Mailman and the Postfix logs to see what your Mailman host thinks is happening.

If postgrey is working as it should, it will initially respond to all mail with a 4xx (retryable) status. The theory is spambots won't retry, but legitimate MTAs will, usually after a delay of up to 15 minutes or so, but some more than an hour. As postgrey learns, it will remember triplets (sender, sending IP, recipient) and not delay them and in addition will whitelist domains that retry successfully more than a few times.

Re: [Mailman-Users] Best way to slow down all the spam to my lists?
Yeah, I wanted to avoid that because non-subscribers often email the list trying to contact the list admins or organization representatives instead. I've tried the first link above up through step 4. Step 5 is adding an additional filter to Spam Assassin and doesn't appear to be directly connected to the first four steps.
