We have a pix f/w and on connecting to SMTP in another interface, it always takes a few seconds before the banner comes up and commands can be issued. There are a few things in the log about denying port 113 from access from the server to the client. I've come across information somewhere that because the f/w is silently dropping the packets the server times out the request and tries again before giving up. There was also mention of a way to have the f/w do something other than silently drop the packet to allow the server to give up more quickly.
Does anyone know what this configuration is?
Thanks,
YL
