[MlMt] Mailmate using wrong network card

[Fabian Blechschmidt]

Good morning everyone,

I have the problem, that mail mate tries to use my virtual network card, 
therefore having a wrong IP address when trying to access a mail server, 
which blocks the connection (or the packet doesn't even reach it)

I have Parallels and VirtualBox installed. Both using a couple of IP 
ranges to do their stuff. Neither of them is using 19.2.168.42.*

My routing table - if I interpret that correctly, says, that connections 
to 192.168.42.146 (which is the mail server), should rund through 
default connection. I understand, that with the domain "my.customer.ads" 
we don't know yet which IP address the server has. I assume (but might 
be wrong here) that we than simply use the default route and change the 
device if needed after resolving the domain.

So in short: Whatever happens inside of MailMate leads to a wrong 
network device to be used when contacting the server.

Any idea what to do or how to debug? Tell me if I can help. I assume I'm 
here until friday.

Thanks in advance!
Fabian
