Conversion size MTA option

Internal size MTA options:   (1-2000)
The  MTA option controls the size of the  conversion entry table,  and thus the total number of conversion file entries  (or entries in the   option in Unified Configuration) cannot exceed this number. The default is 32; the maximum allowed with normal, automatic resizing is 500 (controlled from the  file); the "hard" maximum is 2,000. Attempts to set this option higher than 2,000 will result in using the value 2,000 (with no error message).
