l.e.o migration
Finally got around to migrating lists.evolt.org. This was a lot easier than I had expected. The plan was to set up postfix and mailman on the new server, migrate the lists, redirect all SMTP traffic using netcat from the old server to the new server, and then update the DNS. In preparation, I cleared out the SPF information and set up inetd to redirect the information.
Two problems. By default, inetd only allows 256 connections per minute before refusing to handle any more traffic. This is much too low for our SMTP server. I bumped it up to 2600 connections in a minute (nowait.2600) and that was enough, if not excessive. The second problem was that google and yahoo seem to cache the SPF information so the new server appeared to be an unsolicited bulk mail server. After updating the SPF information and waiting for it to propagate, mail started being accepted by them.
DNS information lists.evolt.org seems to have propagated to most places. Still waiting for css-discuss.org to do the same. After that, I'll cut off netcat and start up qmail on the old server to try to clear the queues. And then we're done.
