By mail delivery target I mean something like the “pipe” program which is used as transport target. > I won't speculate about this further, but I would like to point > out that Postfix is designed to be extensible by pluggging stuff > into protocol interfaces (policy, milter, smtp, lmtp) as well as > the tcp and socketmap lookup table interfaces. I will check for this ways. Today the "pipe” transport is the most easy way for my service. When I reach performances issue with many email per second, I probably will use LMTP server. Thierry

I notice that you are talking about INTAKE (sendmail/postdrop/SMTP commmands) not DELIVERY, so your choice of words is unfortunate. I won't speculate about this further, but I would like to point out that Postfix is designed to be extensible by pluggging stuff into protocol interfaces (policy, milter, smtp, lmtp) as well as the tcp and socketmap lookup table interfaces.

For lower amortised delivery cost you can deliver to a Lua-based LMTP server. -- Viktor.
