14 DAY TRIAL // The free, GTK+ based, open-source, fast, user-friendly and lightweight Claws Mail email client has been updated today, November 6, 2017, to version 3.14.1 for GNU/Linux distributions.
Claws Mail 3.14.1 brings lots of changes, including two new hidden preferences, namely 'hide_timezone' and 'rewrite_first_from.' While the first one is used for setting the timezone of date fields that are sent over the network to an unknown timezone value specified in RFC 5322 §3.3, the second one is designed as a workaround for a limitation of various mail servers with 'overly-liberal parsers.'
"When this is turned on and the Content-Transfer-Encoding is set to 8bit or 7bit, in a message body starting with 'From ' the 'From ' will become '=46rom ' (i,e, encoded form of 'F') and the Content- Transfer-Encoding will be changed to Quoted-Printable. When it is turned off no such modification will be made but it is very likely that an MTA will convert the 'From ' to '>From '," read the release notes.
Updated plugins, improved GnuTLS support
Claws Mail 3.14.1 now enforces the "strong enough" Diffie-Hellman prime for systems that use older versions of the GnuTLS library. The RSSyl, vCalendar, PDF Viewer, and Notification plugins have been updated as well with various new features, such as support for Ubuntu's Unity messaging menu to receive Claws Mail notifications, and it looks like a total of 25 bugs reported by users since version 3.14.0 were addressed.
The manual was updated for the English and Spanish languages, along with improvements for 17 languages, hiding of messages and threads in the Draft folders was disabled by default, a green folder icon will now indicate IMAP mailboxes that display only subscribed folders, it's now possible to attach a file to the templates, and Message-ID will no longer be added to drafted messages.
