Hello (or should that be EHLO? :)) It has been a while since I've had a need to change my Postfix configuration, so I'm a bit rusty. I have searched, checked the configuration, etc. No luck yet.
Is it possible to get Postfix to log the hostname presented to it during HELO/EHLO? Any configuration setting I've missed? Or will I have to change the sourcecode for this? This could be handy for a couple of reasons: 1) I've seen spam-attacks where clients have beeen infected with some malware. Example: I've seen SMTP clients present themself as "raspberry", and it is helpful if I can tell the clients that "Something hidden behind your NAT gateway presents itself as raspberry, that's where you might want to look first." 2) Sometimes when sending emails externally, I won't always know which mailserver has received it. Example: multiple mailservers behind a virtual IP address / loadbalancer. Logging the hostname presented in the SMTP session would cover this. Regards Eivind Olsen
