Summary: Claws falls back to TLSv1 by default when using imap with Starttls
Product: Claws Mail (GTK 2) Reporter: timo <timog24>
Component: OtherAssignee: users
Status: RESOLVED INVALID    
Severity: major    
Priority: P3    
Version: 3.13.2   
Hardware: PC   
OS: Linux   

Description timo 2016-03-04 05:00:35 UTC 
Claws uses TLSv1 when connecting to an imap server using Starttls encryption even when the server offers TLSv1.1 and TLSv1.2

This was tested with different servers/providers

Tested on an up to date archlinux setup with gnutls 3.4.9-1

That would be a libetpan bug not a claws-mail bug. libetpan is the library claws-mail uses to handle imap connections.

Try upgrading libetpan to the latest release, and if that doesn't help, report the issue here: https://github.com/dinhviethoa/libetpan
