Hi.
We need to access external Mail servers for some our users with SNAT. Users with Firewall Client in this case do it perfect.
I had made two protocol rules for POP3, SMTP and specified client set. POP3 access works well but SMTP does not. In the FW-Log I get result code 10053 (No such device or address exists) for this SMTP attempts.
Could anybody explain me what does it mean and what I did wrong.

I had resolved the trouble by myself.
The reason is McAfee VirusScan 8.0 running on the ISA computer and port block was enabled in its Access Protection properties.
