mail-filter/spamassassin: new revision to fix Net-DNS compatibility issues.
With the stabilization of =dev-perl/Net-DNS-1.40.0 (and the removal of the older stable version), a number of problems were introduced in SpamAssassin. There are three upstream bugs with patches against the latest release, v3.4.1, which fix all sorts of DNS errors in blacklist checks, DKIM, and SPF. The major contribution of this new revision is to apply patches from those upstream bugs fixing compatibility with =dev-perl/Net-DNS-1.40.0. At the same time, bug 396307 has been fixed by creating the sa-update-keys directory and assigning it the proper permissions. Thanks are due to Olliver Schinagl, Philippe Chaintreuil, Marcin Mirosław, and Atman Sense who reported and investigated these issues. Gentoo-Bug: 396307 Gentoo-Bug: 579222 Upstream-Bug: 7223 Upstream-Bug: 7231 Upstream-Bug: 7265 Package-Manager: portage-2.2.28
