[Mailman-Users] Optimizing sendmail

Sendmail is extremely tweakable - so much so that the default is for a
low-end server.  You can easily increase speed and efficiency by tweaking
the values in your /etc/sendmail.cf file.

The best tweak is to remove that ident crap call by setting:
  O Timeout.ident=0s

Otherwise 99% of your connections wait for 30seconds before actually doing
