(If this would be better asked on postfix-devel, let me know and I'll repost it there.)
What does Postfix do with a message that has a malformed header? If for example there's a header that's found to contain a line whose first character is alphanumeric (thus not a continuation) but contains no colon, is this treated as a header field, or does this cause the header to end and the body to begin, or something else? I'm pretty sure sendmail, for example, ends the header there and begins the body such that the malformed line is the first line of the body, but I'm wondering what postfix does. If there's consensus among popular MTAs about what to do, maybe this should be documented someplace more formally. Thanks, -MSK
