[pkg-fetchmail-maint] Bug#134745: fetchmail-ssl: could show all criteria causing a "skip"

[Matthias Andree]

I'm afraid this is not going to be fixed anytime soon.

Currently, the "seen" detection is protocol specific, and for some
protocols, detecting the "seen" state requires additional round trips so
will remain unavailable.

Beyond that, for later fetchmail releases, we may go for a client-side
message tracking approach; in such a case, it may get fixed, but it's
too early to make any sustainable statement yet, because the design of
the new code is not yet clear.
