Not unexpected :) <snip> > Specifically, Postfix accepts local submissions in UNIX format > (LF) or MSDOS format (CRLF) format BUT YOU MIST NOT MIX FORMATS. So how does postfix determine what format you are using?

Well, fixing my own application was no problem, once I understood the problem sufficiently. I suspect your are trying to make a point that most php developers don't know basic software engineering, however I still think it a bit strong to expect people that happen to develop on a box that uses sendmail to anticipate this issue. But never mind. If you are expecting me to fix the other odd hundred instances of mail() in applications I had no hand in developing on the other hand, that is just over the top. And what about admins, that don't even know php, but just runs the stuff? As far as postfix is often the forward migration path for sendmail users, I am under the impression that one good enginering practice is not to needlessly break backward compatibility, and in cases where you do, provide a switch for old-type behavior. There are several config parameters with the word "workaround" in them so there is no general policy against that I presume. Perhaps the only problem is that no one has offered a patch yet?
