Line limit MTA option

Message size MTA options:  (integer)
The  MTA option places an absolute limit on the overall number of lines in any message which may be sent or received by the MTA. Any message exceeding this limit will be rejected. By default, the MTA imposes essentially no line count limits; (more precisely, the default limit is the maximum allowed integer, 2&#x2a;&#x2a;31-1).

Note that the  channel option can be used to impose line limits on a per-channel basis. The  alias option (or    alias file  named parameter in legacy configuration) may be used to impose line limits on a per-alias basis. Analogously, the  MTA option may be used to set a limit based on number of blocks in a message.

(Note that the    channel option, if used, may modify the timing and form of rejections due to exceeding message size constraints.)
