hi !

I've got alredy had this problem and i solve it by adding a specified
rule in packet filters that enable SMTP packets outbound from my ISA
server.
By defaults only DNS, and ICMP was define, and FTP is define in your
protocols rules.
When you want ISA server make special request as SMTP you had to define
it in packets filters rules.

hope its help you.

Folks

I have a Windows 2000 advanced server running Micrsoft ISA Server as the
internet gateway. All machines on the rest of the LAN are able to browse
the web and send/receive email.

The machine running ISA server has outlook installed on it to povide
MAPI services to a third party monitoring application and before it had
ISA server installed all ran fine.

Oulook is no longer able to send/receive email and telnetting from the
command line to the relevant ports is also failing. As the machine is
still able to access the web and has no special firewall rules beyond
the defaults, I am wondering if this is an oddity, a bug or a
misconfiguration somewhere.

NSLOOKUP, PING and FTP all work fine, just not POP/SMTP

ISA server has a bunch of rules dictating access to specify by subnet,
group, user etc but all these are non specific.

So, can anyone tell me why I can no longer send/receive email from this
machine?

Thank you in advance.
Regards
