I hope you can assist me in fixing an error in my email system. I was able to save and use in Mail (MAC) POP (port 995) and smtp (port 587). I can send email but cannot receive email. I also see 2 IP address which are not my PC and host IP. What are these 2 IPs (92.118.38.36 & 218.78.72.97) which are located in China and Russia?
Below are the Email Error logs for your analysis.

AlonaG I have the same problem i think is spamassasin becouse if I delete “-o content_filter=spamassassin” and give # “befour spamassassin unix - n n - - pipe flags=R user=spamd argv=/usr/bin/spamc -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}” in /etc/postfix/master.cf.
Maile receive normal.
It’s not Spam Assassin my error log do not mention Spam Assassin.
I think my Postfix and Dovecot are not configured correctly because I don’t know how to configure them if use Let’s Encrypt SSL.
