begin using it.
This puts the blame squarely where it belongs, on the heads of the
developers maintaining vpopmail who completely refuse to integrate
shared library support into vpopmail. They've been sent patches, and
never offered detailed reasons for refusing to integrate.

I've seen *one* patch for this and, IIRC, it didn't apply cleanly to
the current version of vpopmail. I worked on it a bit, and liked the
results, but delaying pushing it into the mainstream release.
One problem is that some programs (including qmailadmin) actually make
use of information in the header files to conditionally compile its
code. To truly move to a dynamic lib, we need to have any program
that links to libvpopmail do so without using vpopmail's config file.
It's not as simple as just making the lib dynamic.
What if we wrote an external program that chkuser could run instead of
having to link to libvpopmail? Would that be a good solution.
Main reason for which I wrote chkuser that way is performance. I don't
feel correct to run an external program each time I've to check a sender
or a recipient (and I don't like qmail forcing everything new to run on
external programs).
Another solution could be to spread vpopmail lib into two or more
libraries, considering a stable core and added functionalities.
As I suppose core changing less frequently, that could help avoiding
relinking so often (you could consider as having only the core as shared
library).
I have rebuilt everything after a vpopmail upgrade/downgrade several
times in the last few months. It takes less than five minutes to
recompile qmail-smtpd for chkuser. That is because I have to wait for
qmail to finish. I sorry but this just doesn't take up a major part of
my work week. I don't see the lack of a shared lib as cause for so much
turmoil.
Some people would still build static linked binarys for
performance/stability even if a shared lib was available. Me ;^)
