Summary: imaplib should convert line endings to be rfc2822 complient
Initial Comment:
When imaplib.append is called, it should convert line
endings from whatever they are (\r, \n or \r\n) to the
format required by rfc2822 (in turn, required by rfc1730),
i.e. CRLF - \r\n.
The email package generates mail with Python "internal"
line endings (i.e. \n), and so if a message is flattened
and then appended via imap improper line endings are
sent.
While some imap servers are ok with this, at least one
(Communigate Pro) mangles the message (all the
headers become part of the body).
smtplib has an example of how to do this.

Couldn't agree more :-) Now uses the much simpler regex.
I'm also going to mark this bug as 'fixed"

By the way, since posting this there was some discussion
about the re used in smtplib. Tim Peters, Tim Stone and
Skip Montareo eventually agreed (more or less) that
CRLF_RE = re.compile(r'\r\n|\r|\n')
was better than the one in smtplib. (I really ought to suggest
that to whoever maintains smtplib as well...)
But anyway, thanks for fixing it. I must say that the imap
servers I have access to are forgiving enough - but it only
takes one...

This is a bug. Can't think how it's managed to survive for
so long (there must be a lot of forgiving imap servers out
there). Anyway,
I've just checked in a fix (based on the smtplib code -
thanks for
the ref.)
And thanks for the bug report.

You may want to contact imaplib's author, (Piers Lauder
<piers@cs.su.oz.au>)
directly about this.
