Hey Rick,

Looks like you're not setting the HELO name during the SMTP session.
The following wiki page may be helpful: https://wiki.synchro.net/ server:mail?s[]=smtp.

These log messages indicate an incoming conntion (receive) activity - Not sending. Sending activity is indicated with the word "SEND" in the log messages.

Sorry for the length of the log file. Do I have a wrong setting or what am I missing?

Do you recoginize the IP address 3.149.229.176? It looks like something just scanning your ports that didn't expect to find an SMTP server there.

I retract my previous reply. Looks like Digital Man is right. It's an
incoming connection, not an outgoing one.

D'oh!

No clue who that might be. The scanning ports sounds more like it.
