We currently have a PIX 515E Firewall & an Exchange server. For some reason, several months back - users behind the firewall have needed to modify their OUTGOING pop3 server within MS Outlook. The outgoing mail server entry needed to be changed to our local Exchange server (i.e., exchange.ourdomain.com server).
Since I'm new to servicing this network and have never worked on a PIX 515E, my best guess is that somehow the firewall isn't liking several different OUTGOING mail server requests, but I'm not sure. Does anyone know if the PIX515E has issues with this and if so, what can I do to fix it? Also, is there a GOOD reference help manual anyone knows of to get started on the command line interface?
Most of these users use laptops & require mobility. In addition to using the local exchange server when they are on-site, the users on this network use other outgoing pop3 servers to check other email sources. I would like to be able to set them up with several different pop3 servers so that they do not have to modify those settings every time they need to come/go to the office.
