dovecot - Oct 2009 - 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.

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 :)
