Minor correction:
When I done "spamassassin -D --lint" and saw the new default DNS check slowing
it down, I thought maybe if I statically set "dns_available yes" in local.cf
would skip the check and thus be much faster.
Well, it did improve, but still averaged like 10 secs for 2k-8k messages which
is still abnormal (compared to 0.1 - 0.5 secs for 2-10k messages on SA 2.53)
Finally, I desperately set "dns_available no" in local.cf and messages are now
average 0.4 - 0.8 secs which is not bad...
This is my preliminary analysis, maybe more to come..
