That wasn't a problem prior to my departure, but apparently it is now.

I've just added an SPF for the domain.

You might need to setup/change a SPF record for that domain. I always
had Google marking my email as spam when I tried to send emails with no
SPF record.

Bout a month ago, I had someone crack a POP password on my private mail server,

I locked it down, and am this weekend replacing that mail server with one
of current vintage, serving the same domain from a linode instance on a
different IP and, obviously, transport network.

I'm finding, though, that gmail is spam-filing the emails I send out,
presumably because they're on the same domain name in the envelope.

Anyone got a pointer to where I go to assure Google I'm on top of it now?

The mail delivers to their inbound MX ok, it just ends up in the spam folder,
even on my business GoogleApps account.  Delivers to Yahoomail just fine.

I checked the new IP in the MXtoolbox RBL checker, and no hits, but does
gmail know what ranges are assigned to VPS providers, like with the cable
swamp, and bias its spamchecking accordingly?
