Sendmail not running? Good question. I would assume it gets queued until sendmail is running again, but isn't queing it a function of sendmail? Bottom line: I don't have an answer.
Good practice? Personally, I'd say no. You may want to divert the STANDARD output to /dev/null but errors too? That really depends upon the application.

Maybe it's an stupid question but remeber... I'm Junior..
I use command line to run programs, and some of them gives a lot of information when, for example, you open a window or other actions. That's really bad because my terminal gets full of unwanted messages, so I use "bin file & >/dev/null"... (1 Reply)

sendmail::milter
Sendmail::Milter(3pm) User Contributed Perl Documentation Sendmail::Milter(3pm)
NAME
Sendmail::Milter - compatibility interface for Sendmail::PMilter
SYNOPSIS
use Sendmail::Milter;
Sendmail::Milter::auto_setconn(NAME);
Sendmail::Milter::register(NAME, { CALLBACKS }, FLAGS);
Sendmail::Milter::main();
DESCRIPTION
This is a compatibility interface which emulates the "standard" Sendmail::Milter API.
FUNCTIONS
The following functions are available in this module. Unlike "Sendmail::PMilter", this interface involves a single, global instance of
milter data, so these functions are called without an object reference.
For each function, see the description of its object-based counterpart in Sendmail::PMilter.
Sendmail::Milter::auto_getconn(NAME[, CONFIG])
Sendmail::Milter::auto_setconn(NAME[, CONFIG])
Sendmail::Milter::main([MAXCHILDREN[, MAXREQ]])
Sendmail::Milter::register(NAME, CALLBACKS[, FLAGS])
Sendmail::Milter::setconn(DESC)
One extension function is provided by this implementation.
Sendmail::Milter::get_milter()
Returns the "Sendmail::PMilter" instance underlying this emulation layer. This allows mostly-unmodified milter scripts to set PMilter
extensions (such as dispatcher and sendmail.cf values). It is recommended, however, that new code use the object instance methods
described in Sendmail::PMilter.
EXPORTS
In order to preserve compatibility with the standard "Sendmail::Milter" interface, all SMFI* constants described in Sendmail::PMilter are
exported into the caller's namespace by default.
(Note that "Sendmail::PMilter" itself does not export these symbols by default.)
