sounds like an Exchange bug or an Outlook bug.

when Evolution encodes the email in base64, it sets the Content-
Transfer-Encoding: header to a value of "base64". You'll see this if you
look at the message sources in your Sent folder.

Outlook/Exchange/whatever is supposed to respect that header. apparently
one of them is not.

I have never heard of anyone having any such problem

might be an exchange bug? might be an evo bug. not enough info to know
for sure.

can you get us a copy of the raw message sources (as extracted from the
Sent folder's mbox file)? then we can check that the lines were folded
appropriately. if they weren't, then it's an evo bug. else it's an
Exchange bug.

there is no such restriction in any of the mail rfcs. headers can be of
any length so long as they are folder appropriately (such that no single
*line* is longer than 1000 bytes)

feel free to hack it any way you want.

anything's possible, but we won't be doing this.
