POP, if I'm not mistaken, uses port 110. Users mail could potentially get marked as spam I would think as they will be sending through the smtp connector. Someone please correct me if I'm wrong.

Exchange 5.5 Sorry if this came through twice. Had to change the text type and re-send. This is a little off-topic. We are about to deploy XWall for Exchange on our front end IMC relays. One of the requirements is that we change the smtp port for Exchange on the IMC's to use 24 since XWall will use port 25 and get the messages first. I guess my questions are: For users using POP or custom applications that are using the Exchange IMC as their relay host, how will changing the ports affect them? Have I just disabled POP by installing XWall? We have locked down all unused ports so I guess I need to open port 24 up to the front end and back end servers as well. Is there anything I need to be careful about or any other gotchas that I should know. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
