Hi All, I don't know what the hell I turned off, but all incoming SMTP mail keeps getting blocked at least that's what it says in the packet filter log. I can see incoming ports trying to connect to 25 but they say blocked. I deleted all rules for smtp, client sets for my smtp servers, everything and rebooted. Then I added them back one at a time. Still shows blocked. Does anyone know if the ISA 2000 cache or meta data can become corrupt and could be the cause of this? Tis, late for me 4:18 PAC. Thank you, Joseph
