Hey, this is quite a bug cause it makes the claws-mail use totaly unusable. I've a few gmail accounts and EACH time I want to recieve or send mails it asks me to accept a new certificate. EACH TIME. Yes, because gmail is alternating 2 certificate. And Claws-Mail replace it each time, asking for me ! And it's 4 intterution each time, 10 seconds between them, when i want to see my mails ! Please, handle that case, please :( http://node.gordo4.com/snaps/ed5d79f93a0a68427745a64291e2d3a8.png
