Moved provisionally to Web Gateway for better attention.
This is the first time I've seen that message. Those appear to be all debug messages. Do you see any error messages or error codes in the server.log?
Those messages you see there are not errors. They seem to be informational messages. The false that you see is simply saying that the smtp server is not using SSL on port 25. That is normal.
Do you get any other messages?
One thing to verify -- login to the web gateway using ssh. Make sure that when you try to netcat to your mailserver on port 25... that you actually get a conenction succeeded message. If you do not, make sure the mail server is listening on port 25, is at the ip address you think it is, and is configured to accept mail from your web gateway's IP address.
webgateway# nc -v 172.16.12.245 25
Once connected to your mail server this way, you can also go about manually sending a test message to validate this from the web gateway:
mail from: email@example.com
rcpt to: firstname.lastname@example.org
this is a test message
and watch it go.
ok thanks im go try this solution and post if the trouble was fixed
