Evo warning -- could it be connect to NetworkManager ??

[William Case]

Hi;

Every time I send or receive mail I get a warning message at the bottom
of my Evolution window telling me "Error while fetching mail".
and "Host lookup failed:pop.broadband.rogers.com:Name or service not
known".  In fact, there never seems to really be an error or problem
fetching mail; it is all there.  The warning goes away after a minute of
two.

I have checked my standard logs and can't seem to see anything
untoward. 

Could this be another NetworkManager problem ??
