[courier-users] zdkim rpm

[Zenon P. <or...@pr...>]

Some seven years ago I packaged zdkimfilter in an rpm,
back then v1.5 for centos 7, which I've been using ever
since. Things have moved on considerably in the meanwhile,
so I have now packaged v3.8. The specfile follows below
and the built s/rpm for el8 can be found at
http://www.provocation.net/rpms/el8/srpms/zdkimfilter-3.8-1.el8.src.rpm
http://www.provocation.net/rpms/el8/rpms/zdkimfilter-3.8-1.el8.x86_64.rpm

Note: courier is compiled and runs either as user/group
courier or daemon. zdkimfilter checks this in ./configure
and is built accordingly. Hence, if the zdkimfilter.rpm
is built on a system with courier-as-daemon and installed
on a system with courier-as-courier or vice versa, things
will probably go wrong at runtime. The binary rpm linked
above is courier:courier 900:900.

Sam, wouldn't it be a good idea after all these years to
simply lay claim to the courier user/group, preferably
with fixed UID/GID, and abandon the daemon alternative?
