# Cyrus delivers claims that the mailbox does not exist

Given that you have a username `john@domain.tld`, unless you escape the ‘@’ as explained below, Cyrus deliver will claim that the mailbox does not exist.

Instead of `deliver john@domain.tld` you should be using `deliver john\\\@domain.tld`.

And instead of `deliver -a john@domain.tld -m user/john@domain.tld` you should be using `deliver -a john\@domain.tld -m user/john\\\@domain.tld`

As far as the ‘@’ is concerned, the same applies while not using the unixhierarchysep.
