I keep getting this error on my ISA Server. In the Data, it referenced xexch50. So after some research, I found I needed to add that to my ISA filter(to get rid of the error) and I nerviously did because I was unsure what and where this xesch50 came from.
Now I get a new error: "A Smtp command line length exceeded its maximum value". I read where the xexch50 length should be no more than 50 so that is what I put but
I get the "length" error. Then I got nervious and decided to go no further until I found out wheather xexch50 is an ok thing or a bad thing. Sure would like to clean up these errors but since they are only warnings, I figure I have time.
Any help or advice would be appreciated. Thanks,
Todd
 
The more I look into this error, I am wondering if I even need the ISA SMTP Filter. I am not trying to screen out words and only the default setup is in place. Is there any problem in just deactivating the smtp filter...
Thanks.
