[Evolution] POssible to clear Evolution's DNS cache?

[Brett Randall <javabrett gmail com>]

Hi,

I have a situation with a VPN where my server's IP address changes 
between connect/disconnect states.  It _appears_ as though Evolution 
caches the DNS lookup for my server, so there are problems when my VPN 
connection state changes (Evolution cannot connect, general 
instability/slowness).

Any workarounds for this - clearing Evolution's DNS cache for example?

Evolution 2.26.1 on Ubunutu Jaunty 9.04.

Thanks
Brett
