SMTP Mystery
-
So I have been using PFsense v2.1.5 for some time but noticed over the last week that my email wasnt flowing just right.
Doing a telnet internally to the SMTP port gives me the standard "220 " response message with the correct FQDN etc data but externally now I am getting a response of "220 *************************************************************"
Any ideas on what could be causing this? My NAT config has not changed from external to internal.
Thanks,

Hi,
Are you saying that NAT (on pfSEnse) isn't working anymore ?
Your postfix server needs a break ?
Postfix is running on pfSense ??? (it might as well prepare you coffee, but, please …. don't try that one)Btw: understand that most of us, if not everybody, do not run 2.1.5, we all use the '2015' version : 2.2.2.

Its great that you use the most recent version but no I am not saying that NAT isnt working anymore.
Clearly from my description the SMTP server is responding to the incoming connection request its just that I am not receiving the banner on the external connection as I do from the internal.
