I do whatever this means:

auth default {
  mechanisms = plain login

####      passdb passwd-file {
####        args = username_format=%Ln@%Ld /etc/mailauth/ALL.deny
####        deny = yes
####      }
  passdb passwd-file {
    args = username_format=%Ln /etc/mailauth/%Ld.deny
    deny = yes
  }
####      passdb passwd-file {
####        args = scheme=crypt username_format=%Ln@%Ld
/etc/mailauth/ALL.passwd
####      }
  passdb passwd-file {
    args = scheme=crypt username_format=%Ln /etc/mailauth/%Ld.passwd
  }
####      userdb passwd-file {
####        args = username_format=%Ln@%Ld /etc/mailauth/ALL.passwd
####      }
  userdb passwd-file {
    args = username_format=%Ln /etc/mailauth/%Ld.passwd
  }

The intention of the above is that these  passwd-file format files have only
the username part of the full email address being logged in as, and a
separate file be there for each domain.  So if I login to IMAP as
phil at example.com, then I would be authenticated by accessing file
"/etc/mailauth/example.com.passwd" and searching for user "phil" in that
file.

I would not expect the formatting of what username I search for in these
files to cause the %d variable to lose its content.
