I don't really like that arrangement, but I'm pretty sure there are real-life MIMEDefang deployments that work that way. Yes, there are :-) Particularly when the number of MTA and mdf servers is large but not equal and the mdf servers run older-style memory file systems.

Re: [Mimedefang] Rejecting Cyrillic

So someone writing in cyrillic and using koi8-r or windows-1251, won't switch to another character set when answering a question on, for example, this mailinglist, using only ascii characters to write english. What's the penetration now for mail clients that send in UTF-8? Will the elephant in the corner (Exchange, OE) do that? Or does it insist on sending in legacy charsets like 1251? Not that I'm sure universal UTF-8 (with no errors) will help, but it's one less complication in the format, and lack of it might eventually become a strong spam sign. Just checked that elephant in the corner and it sent, for example, with: Content-Type: text/plain; charset=ISO-2022-JP Content-Transfer-Encoding: 7bit Hope this helps, Len ___ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
