Cyrus-sasl is a package which provides an API to do various
sorts of authentication supported by different protocols (like
SMTP & POP, which are what we care about in our case).  You
probably wouldn't have heard of it unless you're in the middle
of that stuff.

Got it.

Hmm, as in "inc" will do the fetching for me (so that I won't need
to use "fetchmail" anymore)?  Oh wow, it does!  (It's been a long
time since I read the man page for inc ....  B-)  What are the
"limitations" that you hinted at?

inc can fetch email from POP server ... and in fact, it always
had that capability going back maybe a few decades.  It wasn't
always compiled in, though (more recently we made it always be
compiled in).  I won't bore you with the exact technical
details, but right now inc _can_ do encryption to the POP
server _if_ you use a SASL mechanism that supports encryption
(that's how I use inc).  But most POP servers (including the
one at gmail) use TLS for encryption which currently inc
doesn't support.  There is an option to make it work; people
successfully use the -proxy switch to inc to run a program that
does the TLS for you.  So yeah, you can make it work, it's just
not as integrated as I would prefer.

In fairness I must point out that there are a number of nmh
users who don't feel inc should fetch email from POP servers;
they prefer using fetchmail or an equivalent.  You can check
the mailing list archives for the discussions about that; I
don't think they're worth rehashing again.  Obviously I don't
agree with that view, but I would be remiss if I didn't mention
it.

Okay, I see.

Yeah, I would prefer to use the more integrated flows, so I'm not
likely to switch off of fetchmail in this case.

Thanks!
