Hello,
I'm sending mails with the following header lines:
Content-Type: text/plain; charset=UTF-8
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
(as this one right now, even if the text is plain ASCII because
it is in English),
When I'm using the MTA of my provider 1blu.de, all is fine.
But, sometimes I'm forced to use as next MX a Microsoft Exchange:
$ telnet 10.1.70.200 25
Trying 10.1.70.200...
Connected to 10.1.70.200.
220 Exchange.BKR.local Microsoft ESMTP MAIL Service, Version: 6.0.3790.4675
ready at Fri, 24 Jan 2014 11:47:57 +0100
and this piece of software (or malware) is complaining about the
Content-Transfer-Encoding: 8bit line, saying:
..
<Exchange.BKR.local #5.6.1 smtp;554 5.6.1 Body type not supported by Remote
Host>
I've checked the RFC 1428 for this which gives the above lines even as
an example (only with charset ISO-8859-1 and not UTF-8). And some googling
gave me a link to the M$ pages, which claim
http://msdn.microsoft.com/en-us/library/ms526992(v=exchg.10).aspx
Content-Transfer-Encoding: 8bit
Exchange Server 2003
Content-Transfer-Encoding: 8bit
8bit encoding has the same line-length limitations as the 7bit encoding. It
allows 8bit
characters. No encoding or decoding is required for 8bit files. Since not
all MTAs
can handle 8bit data, the 8bit encoding is not a valid encoding mechanism
for Internet mail.
What should I do?
Thx
matthias
