[MlMt] Mailmate fails to connect after awhile

[Jan Erik Moström]

Here is something that have happened a couple of times the last 18h or 
so. I'm running Mailmate as usual and notice that it can't connect to 
any of my mail providers (several addresses, three different providers).

"OK, your internet is down" you say - well no, all other apps works just 
fine

"OK, something is blocking the ports that Mailmate uses to talk to the 
servers" - I don't think so, if I try with Mail (only have 1 account 
configured) sending/fetching works just fine while Mailmate can't 
connect at all. Also, if I quit Mailmate and launch it again everything 
works just fine.

I haven't touched the OS in any way and it only seem to affect Mailmate, 
does anyone have a suggestion for what the cause could be?
