Apparently my encoding (force UTF-8 in your MUA if it doesn't display as 
Chinese) went through OK then?

Not sure at this point if those are 'otherwise' valid messages, or soem for of 
malware.

BUT -- all of those carry intial strings that are indicative of use of 
non-ASCII 
character sets. The smtp standard very much prefers 7-bit ASCII in the 
'envelope' & headers, and even in 'content' (body and attachments) *unless* 
identified as recognized MIME type encodings.

Exim is more forgiving - it is inherently '8-bit clean', ordinarily just 
ignores 
those *unless* it cannot use them at all.

You mentioned Debian, so if you are using the common Debian-specific 
configuration tools, we may have pinned-down 'a' cause, but I am out of 
suggestions as to where to look for a solution.

A long shot - but given where it is crashing, it might even be related to the 
underlying OS or file system in use.

There is a specialized support mailing list for Debian-Exim, and there should 
be 
more expert solutions there somewhere, as the author's native code-set is not 
ASCII, either, and he is for-sure a Debian user as well as developer.

Wander over there and see what an archive search turns up. URI is in your docs.

Best,

Bill
