[Users] gmail certs

[Bruce Bowler]

I don't know whether it's me, our firewall or claws, but it's making me 
crazy...

OS Win 7
Claws version 3.10.0-2, but also with 3.9.3-84

At least daily, for the last week or 2, I get a popup that there's a new 
gmail cert.  If I'm sitting in front of the computer and catch it, and 
click accept and save, claws continues and life is good (until the next 
time).  If I'm not here, claws spits out a different message (can't 
connect?).  

This doesn't happen with other avenues of getting to my mail (both 
directly as a gmail.com address and also as a gmail hosted business 
account), such as the web interface or the android app.  I assume they 
work as they're written by google and automagically accept the certificate.

So I guess there are 3 questions...

1) is anybody else seeing this daily or more often cert changing on gmail

2) is there a way to identify whether is me, the firewall or claws?

3) is there something else that I might try to get rid of the annoyance?

Thanks!
Bruce
