How much more involved an SMTP server are you thinking vs. LMTP? As I discovered while researching the LMTP protocol, it is literally just SMTP with mandatory pipelining, highly recommended 8bit and chunking and forbidden to use port 25 or operate over any wan links...
In fact, I'd bet that adding a 'case EHLO:' right before the 'case LHLO:' in the alpha LMTP daemon I posted would do the trick! BTW - Did you guys just hack up a simple SMTP daemon, or work with enough structure to run into the insert_messages() limitations which I'm currently working to address with the pipe.c rewrites? I'd be interested to hear your impressions on increasing the flexibility of that code...
