The problem was a combination between the postfix MTA (that was why I couldn't reproduce it locally - its Exim here) and some chenges in the quoted printable encoding function. The strange thing is Postfix not liking CRLF as line delimiter though RFC 822 says it's the right way. I experienced this a while ago in the headers and came across it in the body now. AFAIK all known MTAs are fine with simple LFs, too so I chenged the mail.php to use LFs only. Andi PS: Can anyone give me a pointer on why Postfix (which is a very popular and widespread MTA) behaves that strange?
