I'm trying to allow my PIX515 to allow mail from my inside network to external hosts. I'm in a unique situation where I don't need to allow outbound hosts to send mail to my inside network. However I receive the following error on my PIX:
check the pix and see if the port is open from inside to outside.
you can also check it from any computer on the network by the telnet command to any mail server on the internet whith port 25 . in the command line you shuold write : telnet (internet mail server ip address) 25
if you get the server name than it means that the port is open, if not....
If a correct translation is configure to leave the trafic going out (NAT+Global), then the PIX shouldl allow all outgoing connections, except if you have configure access-list aplied to inside interface.
