Are subdomains in mydestination redundant?

[Chris G]

Currently my mydestination line looks like:-

    zbmc.eu, dps.zbmc.eu, localhost

This is on the mail server which receives E-Mail from the 'outside
world' from whose point of view my system is zbmc.eu.  Is the
dps.zbmc.eu entry actually necessary or will mail for dps.zbmc.eu be
accepted anyway because mail for zbmc.eu is accepted?

There are likely *some* E-Mails sent to some...@dps.zbmc.eu from within
the LAN.
