What the hell? I got this message but when I check my IP in sorbs it says it's
not there. Is something wrong with svr1.postgresql.org?

That's because the PG mail server is setup to block all mail if it can't contact SORBS.

So as the message shows, you are blocked because svr1.postgresql.org was unable to access the dnsbl.sorbs.net DNS.
It returned error 554 Service unavailable. The rbl is set to hard block all mail when it can't talk with sorbs.
Possible reason is they have had a number of DDOS attacks recently.

We're running postfix ... I didn't realize that it doesn't give a 'soft
error' if it couldn't contact the RBLs ... is there a way of configuring
it so that it does?
