Hello, When I enable the SMTP Filter in ISA, people can't authorize to the published SMTP servers in our network. When I try to add the "AUTH" command in the SMTP Filter in the "allowed command list" , it doesn't save my changes. I know this problem is well known (?), but I haven't been so active on this list. So I wonder if someone know if there is a hotfix or a way to solve this problem. TIA. /Lars.
