Hi Gevisz

I had a similar behavior with another tools : offlineimap
It seems that Google changes certificates very often and/or uses
different certificates on different connections

For offlineimap, the solution is to use an option to check certificates :
sslcacertfile = /etc/ssl/certs/ca-certificates.crt

Maybe there is an option to do the same in Claws Mail.
I found "Bug 2199 - Claws doesn't propery verify certification chain"
[1] which affected a GMail user.
It's fixed, so you may find what's been done.
