I have a client who has had a couple of email addresses stop working, and
outlook complaining that the connection had been dropped by the server. I
did some network sniffing and discovered that Outlook was in fact closing
the connection (orderly disconnect). I looked at the actual message, and
the only thing odd that I noticed was that there was no blank line after the
header. The message contained a subject line with no body, but there was no
blank.
I checked out RFC 822 to see if the separator was required, but it seems
ambiguous to me:
A message consists of header fields and, optionally, a body.
The body is simply a sequence of lines containing ASCII charac-
ters. It is separated from the headers by a null line (i.e., a
line with nothing preceding the CRLF).
My feeling is that the sending application (appears to be Lotus Notes) is to
blame for not including blanks and the receiving application is to blame for
requiring them. However, I can't control either of those factors.
Does anyone know of a patch or something that would force messages stored in
the Maildir or MBox formats to always contain this blank line? I'm using
Maildir BTW and haven't tested with MBox. I think this is the right place
to correct the problem since we can't correct the MUA's and this would work
with any pop/imap server.
