[Dovecot] Fwd: Re: "Time just moved backwards" in Dovecot in a Xen DomU
Dunno, your email provider doesn't want to talk to me, heh, screw them :)
They claim i'm on an rbl, no rbl checks verify this. Even tried to
submit a request using their website, but it's broken and doesn't work

yes, using a pool server for that isn't good. but atleast it will let
us know if it's just an internet path, or ALL internet paths for him
that is causing issues, as it should give a good random sampling.
I have a few servers in the pool set to gigabit speeds. If people
configure their settings correctly, the dsl/cable ones shouldn't get
selected very often.
And the pool servers aren't the cause of his issues, as he isn't using
any pools servers.
I think he has a network issue personally.

Jitter stops ntp from doing it's job properly. I'm not sure what is causing you jitter to be so bad, but it's caused by the delay amount changing from packet to packet. The delay should stay consistant (like a ping time). If it keeps bouncing all over the place, ntp can't figure out what time it really is, cause it doesn't know how long that packet was on the network. You can safely ignore offset, it is just how much different your clock is from what the other computer is.
Try adding some of the pool servers in there, like: server 0.us.pool.ntp.org server 1.us.pool.ntp.org server 2.us.pool.ntp.org
this can also be the cause of it all, there is no QA on hosts in pools, I've seen DSL and cable connected hosts in pools causing all sorts of problems for some, I'm lucky enough to be in a position where we have access to atomic servers so I can avoid all that, but most people are not.

Your in a private RBL I use, which is setup to avoid replicating access lists to every SMTP box in the corporate farm, but anyway, the netblock is banned for mass spam over a 6 month period, that block encompasses a /19 so I'd say ur using a spammer friendly host provider... Oh, and the form works *if* you fill in all the required fields :)
