You have complicated things by blanking out some of the data and replacing
it with "user at domain". Please don't. I can see that the address you were
testing is "francis at csluganda.com", so it makes it easier if that is
consistent everywhere. I'll assume wherever I see "local_part=user" that
actually it is "local_part=francis".

Correct - this is a local domain

OK, he's not in your aliases file

The errno is in /usr/include/errno.h; 2 is ENOENT (no such file or
directory). In other words, a file with that name doesn't exist.

There is no user called 'francis' in your /etc/passwd file

OK, that's the directory you get from the lookup, so it's what's in the
database.

Successful match. You have forwarded to a file address,
"/usr/mail/domain/users/user/Maildir/".

OK, then the transport is found too.

Aside: Personally I don't use forwarding to deliver into a /path/like/this/
any more because it's not very flexible (you can't carry information about
uids or quotas along), but it works. These days I record information in
$address_data and the transport extracts the bits out of that it needs.

So now try:

# exim -odf -d user at domain
... type a mail message here
.

to actually perform a delivery to this user; this will exercise the
transport.

If this works OK, then can you be more specific as to *exactly* under which
circumstances mail delivery does not work?

OK, well problems with your domain are a separate issue, but will affect
incoming mail from other systems. If you insist on hiding the domain, we
won't be able to help you...
