Alias expiry alias option

Alias options:
The  alias option is used to add an Expiry-date: header line. The   should be a date and time, in ISO 8601 P format. (The MTA will convert the specified value into the appropriate corresponding RFC 5322 date value needed for the header line.) The MTA&#x27;s periodic return job will  return messages whose Expiry-date: has passed.
