Maybe where you come from.  The last ISP I was with listed all of its
customers addresses as "dynamic", even when they weren't, and the mail server
they provided lost ~10% of all mail and regularly introduced 4-5 *day*
delivery delays to the rest.

ISP-provided mail servers have gotten significantly worse over the last ten
years, to the point that simply saying "relay through your ISP's smarthost" is
no longer good advice.
