25 Hi Gevisz
26
27 I had a similar behavior with another tools : offlineimap
28 It seems that Google changes certificates very often and/or uses
29 different certificates on different connections
30
31 For offlineimap, the solution is to use an option to check certificates :
32 sslcacertfile = /etc/ssl/certs/ca-certificates.crt
33
34 Maybe there is an option to do the same in Claws Mail.
35 I found "Bug 2199 - Claws doesn't propery verify certification chain"
36 [1] which affected a GMail user.
37 It's fixed, so you may find what's been done.
38
39 Best regards
