The mirroring setup is finished. There's a master server now handling
dovecot.org and a mirror server handling www/hg/wiki. Would be nice to
get another reliable fast mirror server if someone wants to donate
one :) Requirements are:

 - Apache2 with WSGI
 - Mercurial
 - Patched moinmoin
 - ssh + rsync so I can push changes immediately

I have a script that builds all of those on a freshly installed CentOS
5.6 (and a kickstart config to do the install too).

hg commit hook calls rsync immediately

www itself doesn't change unless I change it manually. When a new mail
arrives via mailman, it gets rsynced to mirrors within 5 minutes. This
is done by rsyncing the current month's all files/dirs.

Edits are rsynced to mirrors within 5 minutes.

Also there's a nightly script that rsyncs everything just in case
(except in case of mailing list archives only current+last month, since
they're so huge).

BTW. Apparently there's still something wrong with dovecot.org's reverse
DNS record. It appears to be ok, but some DNS servers have cached it
wrong. I don't know why. We've complained to the ISP. Also dovecot.org
is currently sharing IP with some other stuff, but should get its own IP
some day.
