Wrong forum. This is for Proxmox VE. See here: https://forum.proxmox.com/forums/mail-gateway-installation-and-configuration.8/

check the logs (journalctl -b ) there should be a message indicating where the problem is - search for a time when you tried sending to yahoo

pmg postfix/smtp[19070]: SSL_connect error to mx-eu.mail.am0.yahoodns.net[188.125.72.74]:25: Connection timed out

a connection timeout sounds odd - what's the output of:

openssl s_client -connect 188.125.72.74:25 -starttls smtp
