Yes, however I would do it partly in C ("use ZMailer::talib;")
so that all issues related to the transport-specification file
handling (opening, locking, diagnostics..) could be done in there.
The main loop in itself could be left to PERL, or maybe be a
C function called after proper initializations, and it would call
given per recipient and/or per file procedure(s) with parameters
of recipient list, originating envelope, supplied headers, body
start offset, body file path, possible 'verboselog' FD.

Yes, it definitely is doable, but I don't have time for doing
it now (even if I had interest, which I do -- a bit.)
Anybody else ? Person attempting this must be proficient with
PERL's XSUB programming. (I am only moderately good there.)
