I understand it fine. I just have to get as much info as possible for our developers so they can code it up. Just want to make sure they don't have to do a ton of debugging due some subtle mistake somewhere.

You might want to read serialqmtp.c (in serialmail) and qmail-qmtpd.c (in qmail) I am glancing over qmtp.txt and it's mostly quite clear to me, except the stuff about 'safe messages'. If none of the bytes in a safe message can be <0a>, when the hell *do* we see a safe message? Looking at serialqmtp, it seems to just *disregard* this problem and pump the message into the packet. Cool, no more CRLF/LF conversions :) If it's netstrings that confuse you, read http://cr.yp.to/proto/netstrings.txt Greetz, Peter -- dataloss networks
