Re: LIBESMTPD: E-Mail Client on UC Linux ?

Hi all,

sorry about the delay getting back on all this - I've been on holiday 
for the last week and a bit....

libesmtp5 is the versioning within the Debian ports of libesmtp.  They 
should be the same thing as any changes to suit debian are incorporated 
back into the standard distribution.

Indeed it would ... these have not been done to date as there has been 
no demand for them

Robustness is a design goal.  I believe libESMTP to be one of the most 
robust SMTP clients available (at least in the open source world).

Should be no problem.  I have had no reports of anyone doing this to 
date.  LibESMTP is quite small and should work fine with uClibc.  It's 
only dependency is the standard C library and libdl (I detest the use of 
libltdl - libESMTP only uses this bloat as a last resort).  Any patches 
needed to make it work would be welcome.

libESMTP uses a callback mechanism to read messages from the 
application; the example program should give some idea of how this is 
done (the application is also isolated from whether DATA or BDAT is in 
use).  The library itself does not need changing for this - it merely 
provides a standard callback for reading a FILE * or a string.
