Correct, only relay for your own customers based on your own IP ranges,

Yes, some ISPs deny connections to port 25, but that's why there's
'submission' service on port 587 where authentication should be required so
any problem with sending spam directly to recipients is avoided.
This is popular in *some* countries, dont assume its a universal thing,
because it aint. Most ISP's worth their salt have dedicated customer
outbound mail servers, that only accept from their own, if they dont,
they are too smaller operation to be worried about.
That's popular by an increasing number of ISPs, e.g. when they will get
listed in blacklist like UCEPROTECT-L[23], when they aren't able to cope
with tons of spam reports.
um there is likely tens and tens and tens of thousands of ISP's around
the world, we each run our own ISP's based upon how see fit, because
submission might be popular in the U.S or NZ doesn't mean it is everywhere,
I've been running mail servers (for corporate and some large ISP's) for
nearly 20 years now and never even contemplated using 587 because nothing
warrants it, regarding this geographical location.
