i had a couple of questions regarding options on 4.0.2; my first
stop was the FAQ at www.qpopper.org. from where i'm sitting, though, my
DNS says there's no such host as www.qpopper.org; i've checked a couple
of other servers including some at qualcomm.com; there seems to be
something seriously dysfunctional with the qpopper.org domain.
which makes it hard to find the current version of the FAQ. so, question
1 is... does anyone know what's up with qpopper.org?
in addition, here are the questions i was going to look up in the
FAQ....
4.x has a variety of performance improvements over v3. i'd like to
implement as many of them as are safe in our situation. on our
systems, users have shell accounts. "most" users who use POP don't use
the shell access at all, let alone for mail. of those that do, "most"
don't use shell access and POP at the same time. our biggest system
has 15-20k users and about 100k pop connections per day.
the most obvious performance wins are server mode and fast-update.
fast-update is listed in the manual as potentially breaking biff.
if this is the worst problem then, given our setup, i'm more than willing
to enable it. are there any other consequences to using fast-update?
the same holds for server mode: in a sitation like this, there are
potential issues with server mode, but the documentation doesn't
detail them. exactly how serious _are_ they? what's the worst case?
is it something serious (lost mail, vanishing mailboxes) or just
cosmetic?
other performance wins in v4 would be nice to hear comments on.
