Forward data size MTA option

Internal size MTA options:  (1-1000000)
The  MTA option sets the internal hash size for the forward (database) text file entries. The default is 64; the "hard" maximum is 1,000,000. Attempts to set this option higher than 1,000,000 will result in an mm_init error, "FORWARD_DATA_SIZE exceeds maximum". Attempts to specify more forward database entries than allowed by this option&#x27;s maximum will result in an mm_init error, "no room in table for forward data ...".
