ezmlm problem with Received: headers from "ezmlm-send -r"

ezmlm problem with Received: headers from "ezmlm-send -r"

[Christopher Faylor]

In the process of setting things up to deal with an email server at a
new job, I stumbled across a problem with the way ezmlm adds received
headers to outgoing email.

Currently, ezmlm copies the original Received headers to the email
message following all of the other stuff that it puts in the header.
This should be ok but Microsoft ESMTP Mail Service (sigh) seems to delete
everything between the two blocks of Received headers.

If this was just my problem, I'd work around it somehow but I can see
that there might be a number of people out there using this server who
are unable to see many of the headers that ezmlm adds to a message.

Ian or Jason, does this ring a bell with you?  I don't see anything
wrong with what ezmlm is doing but it is a losing battle to expect that
everyone in the world who is using a Microsoft mail server to patch
their servers.

If it matters, the server seems to be:
Microsoft ESMTP MAIL Service, Version: 5.0.2195.6713

Sorry.  I got this wrong.  It is exactly the reverse.  First the special
stuff that ezmlm adds, then the Received lines.  I'm theorizing that it
is the split in received lines that is confusing Microsoft Exchange.

And, wrongness abounds.  I made a simple change to 'ezmlm-send' to
reorganize the headers and that does not fix the problem.  Exchange
seems to be arbitrarily dropping certain headers.  The odd thing is that
when I telnet to port 25 and inject email, the headers come through
unscathed.

I'm surprised that we haven't had more complaints about this.

That is weird to the point of being inexplicable.  I haven't heard of
this problem before.

I think it has something to do with some ordering that I am not getting.
I only saw a List-* survive once and haven't been able to duplicate it
since.  For now, I'm assuming that this is a timesys problem and am
pursuing it as such.

I was sort of concerned that maybe other sites out there were suffering
from similar problems but, in absence of other complaints, I think we
can just ignore this.

Sorry for the noise.
