We’ve recently started using @mail/atmail (windows version) in the office and I needed to change the listening port for SMTP. Basically, there’s no documentation whatsoever regarding doing this, after looking around for the option everywhere I could think of I found this Exim help which suggested the config needed –

daemon_smtp_ports = port(s)

I added this option to the ‘configure’ text file in atmail4\mailserver and voila, everything appeared to work correctly.
I hope this saves somebody a couple of hours of their life 😉
