We are having trouble exchanging e-mail w/ another PIX user. This is the only host we have trouble communicating w/. The e-mails usually come through eventually, but there is a long lag (12+ hours). There is no indication of problems at the e-mail server.
We're wondering if "Mail Guard" could be the problem. I was considering disabling the fixup SMTP. What are the security repercussions? Does this sound like a possible fix to our problem? Any other recommendations?
We actualy had the same problem at another site that I used to work at. We resolved the problem by upgrading the PIX to a newer version. After searching the Caveat section of the CCO site we found one that describes what you we were (and you are) running into. Hope that helps.
