The previous line is mostly the same, only it says permit. I posted all the
lines for the given QID.Looking at the logs for other errors the only thing I
see is that occasionally (but far less than the number of lookup errors) was
"(address resolver failure)" and ,mysql connection issues when I was stopping
the various services. And to was not just freebsd.org that failed, it was most
things.
After several hours last night and this morning with a trickle of mail coming
in and several reboots I finally got it working with a manual shutdown of all
the related services, a removal of several ancillary ports (spamassin, etc) and
rebuilding those ports. And then manually starting the services back up.
Nothing showed as an out of date port, but spamassasin, at least, showed
something that was updated instead of installed.
Haven’t gotten a recourance in just about an hour.
Still don't know what the cause was and find it rather concerning because of
the reboots.
When I can get there in person, I'll reboot again and see if all comes back up
this time.
