Your conclusion is correct.  They have been blocking
port 25 outgoing from their customer's sites for years
and started blocking port 25 connections incoming
to their customer's sites last June.  I switched to
eol.ca early in July.  (It took a couple of weeks
because the first time I called sympatico tech
support I was assured that they had made no change
to their blocking strategy.)  Blocking outgoing smtp
was no problem, it just meant relaying through their
mail server.  Blocking incoming smtp  broke email to
private domain addresses supported by a dynamic IP
DNS listing.
