Handle DKIM with eQmail or derivatives and alternatives.

Name conventions:

• *qmail is a synonym for qmail, netqmail, eQmail, s/qmail and similar packages
• OMAILHOME is the home directory, in qmail-1.03 '/var/qmail', include the sub- folders hierarchy.

qdkim is a plugin for *qmail like mail servers. It consits of libqdkim and some wrappers around it. qdkim consolidates the formerly published packages xdkim and qmail-xdkim. Thus, the consolidated packages became obsolete. The change log from the old ones are appended to the package change log.

libqdkim (xdkim) was forked from libdkim. In 2016 the libdkim project was marked in-active on sourceforge. The last version available was libdkim-1.0.21. The code was stripped down, all WIN32 stuff was (hopefully) removed. The shared library functionality is gone. The 'library' is linked statically against libqdkim now, an executable like the former libdkimtest.

qdkim is available as part of openqmail.
