The E2k 2nd nic is necessary purely to bypass ISA when internet clients are
trying to pop3 to the E2k server. (work around)

ISA doesn't use this interface.

Is 10060 authentication denied on the ISA or Exchange.
Clients can pop3 the E2k server when not going thru ISA???

Therefore, is there somewhere in ISA re: authentication methods for POP3 to
E2k??? that may be different to the way internet clients connect.

E2k POP3 is config'd for Plain Text auth currently.

Now you're mixing your network tenses.
If you telnet to the ISA server, the ISA will log that connection attempt.
Also, if you connect to the ISA, the E2K server won't see the connection on
its new external NIC.

Put the E2K server back on the single NIC.
Leave it behind the ISA.
Troubleshoot one thing at a time.

Check your Exchange setup; 10060 is:
Event ID
10060

Event Message
Permission denied. The remote server refused access to the requested
resource. Contact the administrator for the remote server and report the
problem.

I have now tested from a simple pc on the network between isa server and
adsl with the exact same result... telnet Isa ext IP, screen goes blank
then says connection lost.
Those log entries I e-maled to you appear to be the attempts.

NB. Interesting thing. The E2k server now has 2nd nic in the 172.x network
(isa ext network) and ADSL router has 110 directed to the E2k server. ISa
appears to be logging the traffic from the ADSL to E2k server???
Does Isa packet sniff or log all traffic that passes on its network??
