I told you the answer in my initial reply, but to reiterate with more
detail, the copy of your reply which I received by direct Cc: has the
header:

Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes

This means that the text may have been (was in this case) wrapped and a
trailing <space> added immediately preceding any inserted <CRLF>. See
RFC 2646 <http://www.faqs.org/rfcs/rfc2646.html> for details.

Then, your first paragraph was sent as

You may not see it, but the first two of the three lines end with two
spaces. The format=flowed and delsp=yes parameters tell the receiving
MUA that each line that ends in a space should have the space removed
and be joined to the following line making

>Interesting. The only email that I send out that gets wrapped is stuff that goes through Mailman. I can send the exact same thing to a postfix alias of exactly the same people, and it doesn't get wrapped.

The problem is that prior to Mailman 2.1.10, the format=flowed and
delsp=yes parameters were not preserved in the outgoing message, thus
the receiving MUA doesn't unwrap the lines per RFC 2646.

So, I suspect you are seeing this issue on a pre-2.1.10 Mailman. Note
that the loss of the format=flowed and delsp=yes parameters most
likely occurred when msg_header and/or msg_footer was added to the
message, and if you set these 'empty', the problem will be avoided.

>In fact, I'd venture to guess that this email, which is sent to the list and to Mark and I on the Cc: will show up wrapped on the list, and not wrapped on the Cc's.

So did you receive a copy from this 2.1.10 list? If so, what did it
look like?
