"No such file or directory" is a standard Unix error text for a single
error code, ENOENT, defined in /usr/include/asm/errno.h on my Linux
boxes.  Don't read too much into the "or directory" part if the code
concerned is not trying to work with a directory :-)

I think this issue may be a version of something I tried to report
some weeks back, which someone (Ken? I forget) thought might be
hardware related, and then found a workaround for that was 'good
enough' for me for the moment.

The issue for me was that (based on my experiments) the default domain
should not be passed to LMTP, only the other non-default ones.  Any
other approach generated the error message you are reporting.  I
suspect that had your RCPT TO: line read

> 20776 >>> RCPT To:<+sharedfolder>

it would have been accepted just fine!  I do not know why that is -- I
suspect some form of attempted backward compatibility?

What I did to "fix" this here was a small, quick and slightly ugly
patch to the sendmail sendmail-cf/m4/proto.m4 file, causing it to send
the @domain part of the recipient address on to LMTP for all domains
*except* the default one.  I had every intention of going back and
really figuring out what is going on well enough to report it in a
clear way that makes more sense to the developers at some stage... but
so far I have not found (or made?) time to do so.

In case it helps, here is my patch.  It helped for my situation.
