Hi Thomas,

Well... perhaps not.

The attached patch sets the timeout for the getauth() stage (which entails  
STARTTLS-like negotiation). Please try that too and see if you get timeout  
reports while fetchmail tries to negotiate TLS. It should.

Thanks for the report and offered help in debugging. Would be good if you  
could report back in a month or so :-)

Best regards
