if that would be true how comes that most mail clients still default to
25 for submission and years after closing port 25 on our mailserver i
still struggle with customers smartphones still not using 587?

in fact 10 years ago some ISP's *tried* to kill outbound port 25 because
there is no point in using it from a homemachine and at that time we
struggeled also to explain our customers that 25 is plain wrong

finally they gave up because the damage of open port 25 is killed with
dnsbl but the customer support went crazy with "why can't i send email
with my internet connection"

that's a completl different story
