Which would affect all other outgoing mail on my server, right? The
firewall isn't dropping ident tho and all other list mail and private
mail goes right out at about triple the speed of this one list's
outgoing mail. The list in question has members from all the major
ISPs, AOL, Earthlink, Comcast, Roadrunner, Verizon and several dozen
small domains as well. All the mail from that list has the same slow
delivery time, I've watched the queues carefully to see if it's one or
two or even three particular ISPs but it's not, it's all across the

Yes, that's my thought now too since it's affecting both lists hosted
on the same domain and nothing else. I'm going to look at that
domain's DNS tonight (have to go to $DayJob now) and see if there's
anything wrong there that may be causing this.
