Hi, Im having a rather annoying problem getting exchange server
(sbs2000) to recieve inbound smtp. Here's a brief summary:
New Server with a new SBS2000 installation, we're using ISA Server
(which is working as a proxy and firewall) and exchange server using
the smtp virtual server. Internal email works fine, and sending
external email works fine too I can't seem to get inbound email to
work. Server has 2 nic's, 1 connected directly to ADSL router and
server has a static external ip. The other nic is connected to the
switch. I had my ISP change the mx records to point to the external ip
of the server, this worked fine as I was able to navigate to OWA using
mail.domain.com/exchange. I tried several things but still cannot
recieve email from the internet. Port scan shows port 25 as open
however I cannot telnet the port either externally or internally.
Things I've Tried (not in order):
Done port scan via grc.com and port 25 is stated as open
Enable Packet filters/Disabled them
Secure Mail Server Wizard
Tried disabling ISA Firewall service
Uninstalled McAfee Groupshield
Reinstalled ISA Server
Reinstalled Exchange Server
Restart ISA Services after changes
Restart Exchange Services after changes
is there anything I am missing? Have I overlooked something? Does
anyone have any suggestions as what I could try? Any help would be
much appreciated as I seeming to be making no progress whatsoever.
Thanks
