-d37.1

Synopsis

Options can be set on the command line or in the configuration file. The -d37.1 (a.k.a. -d37) debugging switch allows you to watch each option being defined. As each is processed, this message is first printed, without a trailing newline:

setoption: name (char).sub =val  

Here, name is the option’s multicharacter name, char is its single-character equivalent (or a hexadecimal value if it is non-ASCII), and sub is the subvalue for that option if there was one. Finally, val is the value being given to that option. If the option has already been set from the command line and is thus prohibited from being set in the configuration file, sendmail prints:

(ignored)

(unsafe)

If it is unsafe, sendmail checks to see whether it should relinquish its current privileges. If so, it prints:

(Resetting uid)

A newline is then printed, and the option has been defined.

setoption DaemonPortOptions (O)=Name=MTA
Daemon MTA flags:
setoption DaemonPortOptions (O)=Port=587, Name=MSA, M=E
Daemon MSA flags: NOETRN

The first setting of the DaemonPortOptions option sets no modifier flags so the line following it shows no flags. The second setting of the DaemonPortOptions option sets the ...
