IDENTPROTO

See Timeout.ident in Timeout.ident (V8.6 and later) on page 1104 port

Defining IDENTPROTO neither includes nor excludes RFC1413 code. All it does is change the default value for the Timeout.ident option (Timeout.ident (V8.6 and later) on page 1104):

APPENDDEF(`confENVDEF', `-DIDENTPROTO=0')     ← set Timeout.ident=0 by default
APPENDDEF(`confENVDEF', `-DIDENTPROTO=1')     ← set Timeout.ident=30 by default

If you are running a precompiled sendmail binary, you can use the -d0.10 debugging command-line switch (-d0.10 on page 543) to determine whether IDENTPROTO support is defined (if it appears in the list, it is set to 1). New ports should be reported to so that they can be folded into future releases.
