Further, see that the first NOTE on page 19 of RFC 2046 is what enables
you (at least in theory) to have multiparts that are not broken by CRLFs.
Yes. But, having an imapext archive handy, I looked at it now. The x-mailer
fields from the first three messages that break the rule are:
X-Mailer: Mozilla 4.61 [en] (WinNT; U)
X-Mailer: Mulberry (MacOS) [2.0.0b2, s/n S1-000001]
X-Mailer: Mozilla 4.72 [en] (WinNT; U)
The IMAP torture test message also breaks it - ther's a GIF image you
can't decode without the trailing CRLF.
I infer that a MUA can't assume that a missing CRFL at the end of a
body-part means anything.
