Er, how can you send mail without Exim receiving it? OK, it doesn't
need the daemon code, but that isn't very large. It could separate out
the SMTP code for the case when you aren't passing over the message
using SMTP, but that's about all.
Given that memory is so cheap these days[*], and most machines have oodles
of it, and the Exim binary isn't really big by today's standards (my
running version on Solaris is about 0.5Mb; compare Pine 3 at 1.7Mb and
Pine 4 at over 4Mb - I dread to think what this means for Pine 5), I am
not convinced that splitting things up would actually make Exim faster.
Given that it had to load modules, it might even make it slower.
