Re: [PATCH 21.5] Add files for distribution packaging.

Technical aside: That's because Google is already backed off to more than 24 hours between retries, and the greylisting whitelist expires at 24 hours. I don't understand why that happens so quickly, though. Normally an MTA will back off 4, 8, 12, 24, 24 hours for a total of 6 tries -- it should easily get through on the first retry, and you get a second shot on the second retry. Maybe it's because Google has multiple MTA IP addresses (that's how most greylists identify the sender system)?

I hope that I'm now going to have more time to work on our infrastructure. My masters students just handed in their last drafts, so they'll be making a lot fewer demands on my time. Maybe. (I've always wondered why advisors aren't allowed to just write the damn theses for them -- it would take so much less time and effort -- and this year I've thought that more often than in the last 25 years combined :-( .)
