syslog_name is good for any 'constant' information.
Postfix limits the length of a syslog record, and the limit is not
documented. Originally this was done to avoid a buffer overflow in
some historical syslog client implementations, but truncation also
slow down a logfile flooding attack.
With non-syslog logging, the Postfix msg_logger library module
will truncate logging just like the syslog client does.
