Problem solved. My ISP DNS was fine.. took me a while but I tracked down the
problem.
I am connected to my workplace via VPN. This automatically configures their
DNS servers on my DNS server list.
James was auto-detecting and using there servers for blacklist lookups. Due to the
slow nature of VPN (specifically on my
work's network), their DNS servers always timed out (even after 60 seconds) which led
to extremely slow mail delivery.
I fixed the problem by hardcoding my ISP DNS servers into config.xml and
disabling autodiscovery.
Thanks for your help,
Gili
