Alias member size MTA option

Internal size MTA options:  (0-40000)
The  MTA option controls the size of the index  table that contains the list of alias translation value pointers. The total number of addresses on the right hand sides of all the alias definitions in the alias file, or addresses on the right hand sides of all named alias groups in Unified Configuration, cannot exceed this value. The default is 320; the maximum allowed with normal, automatic resizing is 30,000 (controlled from the  file); the "hard" maximum allowed is 40,000. Attempts to set this option higher than 40,000 will result in an mm_init error, "ALIAS_MEMBER_SIZE exceeds maximum". Attempts to specify more alias translation values than allowed by the maximum for this option (normally, the automatic, resizing maximum, unless a higher maximum has been explicitly configured) will result in an mm_init error, "no room in alias member table for alias ...".
