"debian-security-support, the Debian security support coverage checker,
has been updated in jessie.

This marks the end of life of the Enigmail package in jessie. After
many months of work to try backporting the various changes and fixes
required to ensure a secure Enigmail package compatible with the
newest version of Thunderbird now shipped in jessie, it is the LTS
team's opinion that the changes are too intrusive to ensure the
stability of the distribution as a whole.

While Enigmail is still available on addons.mozilla.org, we do not
recommend that package is used, as downloads and executes arbitrary
binaries from the internet without the user's knowledge. It also
doesn't respect's Debian commitment to free software, in that it is
not buildable from source.

We instead recommend you upgrade workstations needing Enigmail to
Debian stretch where proper updates are available.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
