Hi all
I have a problem. Optus@Home in Australia (one of two cable internet
providers) have decided to firewall port 25 traffic (incoming) to
their entire network except for their own mail servers. This means my
mail server is virtually useless. They have blocked smtp traffic since
their entire IP range was being listed with ORBS and other open relay
databases since their users were operating open relays. I'll agree,
the network is run like crap since Optus let this happen in the first
place, but the other alternative (Telstra) is not any better by a long
shot.
I have provided a temporary work around, setting up my work mail
server as the primary MX then routing to a different port, on my
Optus@Home server, which I am now running qmail on. This works, but it
is not very nice. Does anyone have any ideas how I can get out of this
problem with Optus firewalling port 25?
Or is the way I have just described the only perceivable way of doing
this (the latter would be my thinking, but I ask in hope of the
former). It would be nice (however dumb and time-and-resource-wasting)
if I could tell clients coming to my server to use a different port
for their SMTP connection, but I haven't seen anything even slightly
to this degree in all my walkings.
Thanks in advance
