hi
due to some reason hotmail has gone crazy and blocking us continuously for
a month. they claim that some spam email originated thru our server.
however there own SNDS shows us as all green.
for the past 10 days i have put hotmail.com in badmailto so that non of my
users can send to hotmail.com
we have gone thru send logs and nowhere is hotmail seen
still their support keep parroting the same typical answer.
changing my dns settings means a lot of problem
a lot of hardship to all my clients
so i need to know if there is some way by which i can change my OUTGOING
SMTP server ip address while my users continue to smtp authenicate using
the same email server settings.

If you have another server that's sending ok, you could use that one as
a smarthost to relay email to hotmail. Simply use the smtproutes file in
this case to route hotmail messages via your other server. Use of
account name and password is recommended for relays.
Alternatively, provided you have an additional IP address available, I
*think* you could add a 2nd IP address to your QMT host's nic, then
change your routing table to use the alias device/ip as the gateway. I
haven't done this myself, but I *think* it would work. Someone please
correct me if I'm wrong about this.
The best solution of course would be to get things working with hotmail.
I realize that can be difficult at best given their support. You may
need to set up recordio on a session to see what's really going on with
your smtp sessions with them. Provided that your SPF and DK/DKIM isn't
misconfigured, you might have a look at your settings related to
qmail-remote (man qmail-remote), such as helohost and your tls
clientcert.pem. I haven't heard of tls being a problem, but you might
try turning tls off for hotmail and see if that helps.
