[Mailman-Users] Messages delivered out of order and delayed

[Veronica Morris]

Ugh, now all hotmail users are being unsubbed because of bounce action.
I'm guessing this may be related to the problem of delayed messages for
gmail users?  I contacted hotmail as suggested in the help for mailman.

Didn't know dreamhost could be doing more!  If what they did doesn't fix
the problem, I'll contact them and ask them about the DKIM signing.
