The clients site: Exchange 5.5 sp3 on Win2k sp2 connected to the net by a
T1,
running through a firewall router and ISA server sp2 also.
I have the SMTP NOOP command blocked on the ISA server. Over the last few
months, no NOOP command issues.
Two days ago, NOOP command-block alerts from the ISA server, 1-2 an hour. I
checked with the ISP, and they do not use this command. Any ideas? I hope
this is not causing problems like lost emails.
Thanks,
Ty
