Hi, Jim

Well, I'm back... Looks like something else is still wrong.

Here are some more details.

My ISA is having two IPs assigned: 193.231.227.162 and .163. .162 is the
default IP address. On each I have assigned a different domain name: 162 =
domain1 and 163 = domain2. ISA Server is visible outside with the first
IP, the one with .162. The name server, as per my DNS setting and as per
my registrator, is on the .163 IP. Mail server is serving for domain2.

Our company wants a second mail server for domain1, which will be
published thru .162.

I've made all the settings as instructed, but emails still can't get thru.
If nslookup with packet filter enabled, everything's OK: I get all the
records from my DNS.

I have 2 mail server publishing rules, one for each external NIC and both
rules are redirecting SMTP traffic to the same Exchange server. Also, I
have a packet filter allowing SMTP packets on both direction, on default
external IP.

What have I done wrong ? What I have to change in order to have 2 exchange
servers published thru this ISA Server ?

TIA

Alin
