Oscar,
I think port 465 requires TLS and doesn't negotiate via STARTTLS,
perhaps remove STARTTLS from your config?  (I have DAEMON_OPTIONS for
port 465 with M=Eaps, which I think is normal for that port - I did this
like 15 years ago ;) )

If it works, please share so other dma users that experience a similar
issue, may benefit. :)
Kind regards, Dewayne
