Channel table size MTA option

Internal size MTA options:   (1-8192)
The  MTA option controls the size of the channel table. The total number of channels in the configuration file, or the total number of named channel groups in Unified Configuration, cannot exceed this value. The default is 256; the maximum that the MTA will allow with normal, automatic resizing is 2500 (controlled from the  file); the "hard" maximum (only achievable via explicit manual configuration) is 8,192. Attempts to set this option higher than 8,192 will result in an mm_init error, "CHANNEL_TABLE_SIZE exceeds maximum". Attempts to define more channels in the MTA configuration than allowed by this option&#x27;s maximum (normally the automatic, resize maximum, unless a higher maximum has been explicitly configured) will result in an mm_init error, "no room in channel table for ...".
