mailx-12.5-19.el7

The mailx packages contain a mail user agent that is mostly used to manage mail
using scripts.

Fixed bug(s):
* Previously, the mailx mail user agent did not split non-ASCII message headers on multi-byte character boundaries when encoding into the Multipurpose Internet Mail Extension (MIME) standard. As a consequence, the headers were incorrectly decoded. This update modifies the MIME encoding function so that it splits headers into encoded words on multi-byte character boundaries. As a result, mailx now sends messages with headers that can be properly decoded.
