DNS error - pmg-smtp-filter

[thiagotgc]

For some days now I have been having problems with DNS in my PMG.

For no reason, why nothing has changed in those days.

See the syslog log

Jun 29 13:07:18 pmg pmg-smtp-filter[31382]: WARNING: dns: sendto() to [208.67.222.222 ]:53 failed: Invalid argument, failing over to [1.1.1.1]:53

This appears many times in a row, and suddenly my pmg server stops, and I need to restart

Any idea?

can your pmg resolv downloads.apache.org?

can your pmg resolv downloads.apache.org?

root@pmg:~# ping downloads.apache.org
