Claws Mail 3.10 发布了，主要改进内容包括：
Auto-configuration of account email servers, based on SRV records, is now possible. (GLib >= 2.22 is required);
Complete SSL certificate chains are now saved, and if built with Libetpan 1.4.1, the IMAP SSL connection's certificate chain is made available. Both of these allow correct certificate verification instead of a bogus 'No certificate issuer found' status;
A new Libravatar plugin was added, which displays avatars from https://www.libravatar.org/;
Added a preference to avoid automatically drafting emails that are to be sent encrypted (Configuration > Preferences > Compose > Writing);
Messages saved as Drafts are now saved as New, highlighting the Drafts folder, in order to draw the attention to unfinished mails there;
It is now possible to add a 'Replace signature' button to the Compose window toolbar;
Quotation wrapping and undo/redo in the Compose window has been improved;
'Reply to all' now excludes your own address;
The 'Generate X-Mailer header' option has been renamed 'Add user agent header' and applies to both X-Mailer and X-Newsreader headers;
'Check for new folders' now only updates the folder list, not updating the contents of folders. If needed, it can be followed by 'Check for new messages';
The GPG keyring can now be used as the source for address auto- completion;
