Hi,

exim refuses to deliver e-mail to local user accounts which have
backslashes or capitals in the account name. It looks like the
recipient's local part is lower cased and has backslash expansion done
to it before check_local_user compares against the local user database.

This makes delivery to user names like Debian-exim and or
DOMAIN\foo impossible.

For backslashes, this can be remedied by doubling the backslash
(DOMAIN\\foo). There is no remedy for the capital case.

Greetings
Marc

We decided not to do this and not being able to e-mail Debian-exim in
the default configuration. This is documented in the README.Debian file.

That is natural according to the SMTP RFC, no need to document.

Closing this bug.
