Are you using exim4? When reading documentation for that last night
I saw the following section:
(in file /usr/share/doc/exim4-config/README.Debian.gz)
-------------------------------------------------------------------------
2.1.1.10. Keep number of DNS queries minimal (Dial-on-Demand)
In normal mode of operation Exim does DNS lookups at startup, and when
receiving or delivering messages. This is for logging purposes and
allows keeping down the number of hard-coded values in the
configuration.
If this system does not have a DNS full service resolver available at
all times (for example if its Internet access is a dial-up line using
dial-on-demand), this might have unwanted consequences. For example,
starting up Exim or running the queue (even with no messages waiting)
might trigger a costly dial-up-event.
This option should be selected if this system is using Dial-on-Demand.
If it has always-on Internet access, this option should be disabled.
-------------------------------------------------------------------------
If you think this might be related to your problem you can attempt to
reconfigure by running the command
dpkg-reconfigure exim4-config
Just keep everything the same other than the screen that asks about
the above feature.
