Unhandled exception when being blocked by gmail.com

Hi,

I got an unhandled exception with Getmail while fetching emails from
gmail.com, while Google blocks the IMAP request to tell the user that
they connect from a different network than usual.

While receiving such an error from Google is (unfortunately) quite
normal, I believe that getmail should handle this case more
gracefully.  I think it should display the error message provided by
gmail.com, instead of throwing an unhandled exception without further
details.


Regards,
Volker
