So if I understand right you suspect that my ISP is filtering out the
SMTP packets.
My problem is the other way around.
When I try externally (telnet to yyyyyy.131 port 25) it works
When I try on the OpenBSD host (which is the firewall itself) it does
NOT work.
It looks like for me OpenBSD 5.6 does not passing up packets to pf which
destined to self.
Maybe its a bug in 5.6 as it worked in 5.5, but maybe it is a change
that I did not notice in the changelog.

If y.yy.yy.131 is your External Interface (attached to your cable modem, (or
what ever), you
should test from somewhere else, such as your cell phone NOT connected to your
wifi, or a shell
on some remote machine.
I say this because connections "out-the-in-again" are commonly being blocked by
some modems
these days. In particular I have this problem in Comcast, and have torn more
than a few hairs
trying to fix it, only to find it was intentional on their part.
