Map names size MTA option

Internal size MTA options:  (1-1000000)
The  option specifies the size of the mapping table name table, and thus the total number of  mapping tables cannot exceed this number. The default is 32; the maximum allowed with normal, automatic resizing is 5000 (controlled from the  file); the "hard" maximum is 1,000,000. Attempts to set this option higher than its maximum of 1,000,000 will result in an mm_init error, " ".

Attempts to specify more mapping tables than allowed by this option&#x27;s maximum (normally the automatic resizing maximum, unless a higher maximum has been explicitly configured) will result in an mm_init error, " ". In particular, note the following. In its literal meaning, the " "  error indicates that your configuration&#x27;s current MTA internal table sizes are not large enough for your current number of mapping tables. However, also note that formatting errors in the MTA mapping file can cause the MTA to think that you have more mapping tables than you really have; for instance, check that mapping table entries are all properly indented.
