Today I’m having strange a behaviour of MailMate. When sending
emails to a supplier I get this error:
Action: failed
Status: 5.6.1
Diagnostic-Code: smtp;554 5.6.1 Body type not supported by Remote
Host
I don't know whose fault that was, me or their servers?
Both.
I assume that text is coming in an email "bounce" notification. Usually
such messages include other useful details about which machine replied
with that "Diagnostic-Code" message, which indicates that you probably
need to send your mail in a more traditional form: try pure plain text.
Technically, this is probably because your outbound mail server provides
support for one of the mechanisms that let senders skip Base64 or
Quoted-Printable encoding of anything other than 7-bit ASCII characters
(there are actually 3: SMTPUTF8, 8BITMIME, and BINARYMIME.) MailMate
will send "raw" 8-bit message parts if possible, but since not all mail
servers support one or more of those transport extensions, it may not be
possible for your immediate outbound server to hand the message off to
the next hop.
