There is a placeholder %m, which gets replaced by a complete
chain of a progressively stripped e-mail address, e.g.:

  user+foo at sub.example.com
  user at sub.example.com
  user+foo
  user
  @sub.example.com
  @.sub.example.com
  @.example.com
  @.com
  @.

or by setting $ldap_lookups_no_at_means_domain to true,
into a:

  user+foo at sub.example.com
  user at sub.example.com
  user+foo@
  user@
  sub.example.com
  .sub.example.com
  .example.com
  .com
  .

A query filter template like:
  (&(objectClass=amavisAccount)(mail=%m))
gets expanded into an OR of all mail=%m comparisions, e.g.:
  (&(objectClass=amavisAccount)(|(mail=v1)(mail=v2)...(mail=vn)))

So if you only have full domains listed in LDAP, then only domains
get compared, full email or subdomains will never be able to
match any domain name in a database.
