IMO, nowadays defaulting to port 25 is deprecated. RFC 8314
https://datatracker.ietf.org/doc/html/rfc8314 defines as default the 465
(with TLS). The 587 (with STARTTLS) is mentioned only as fallback, but
this is not important here, as users have to have possibility to set,
what they need/want.

I will ask to take this change, as previous discussion shows, port 25
can cause problems for not experienced users, it is often blocked by
ISPs or applying strict rules by MTAs.
