I still can see no upgrade to your version of claws, from where did you install it?
I have extras-devel activated.
I would like to upgrade to your version to test if it is still working here...
The server for receiving and SMTP server field shouldn't have @gmail.com. It should be imap.gmail.com for receiving and smtp.gmail.com for SMTP. As for the ports, it should be 587 on SMTP and 143 for IMAP. Both use SSL but don't select STARTTLS since it's not supported(?)
