BUFFER SIZE TCPIP-channel-specific option

TCP/IP-channel-specific options: BUFFER_SIZE (integer)
(New in MS 6.3.) The  option is available for the  LMTP server only. It sets the buffer size for the LMTP server to do in-memory buffering of incoming messages, overriding the default 1,000,000 bytes. Thus this LMTP server option is analogous to the    MTA option which controls similar buffering for components other than the LMTP server (and has no relationship to the MTA option with a similar name   but a completely different meaning).

Messaging exceeding the limit will be written to a temporary file and the temporary file will then be mapped into memory.

In unified configuration the option can be set as follows: msconfig&#x3e; set channel:tcp_lmtpss.options.buffer_size 1000000
