sendmail -q [-v]
-bp Print a listing of the queue.
-q[time]
Processed saved messages in the queue at given intervals. If time is omitted, process the queue once. Time is given as a tagged number, with `s' being seconds, `m' being minutes, `h' being hours, `d' being days, and `w' being weeks. For example, `-q1h30m' or `-q90m' would both set the timeout to one hour thirty minutes. If time is specified, sendmail will run in the background. This option can be used safely with -bd.
or
mailq
If invoked as mailq, sendmail will print the contents of the mail queue.
DeliveryMode=x
Set the delivery mode to x. Delivery modes are `i' for interactive (synchronous) delivery, `b' for background (asynchronous) delivery, `q' for queue only - i.e., actual delivery is done the next time the queue is run, and `d' for deferred - the same as `q' except that database lookups for maps which have set the -D option (default for the host map) are avoided.

To see whether the MTA is willing to accept mail for the user in question, you need to have shell access on the mailhost and run this there:
$ sendmail -bv username username... deliverable: mailer local, user username
If you get an answer mentioning a remote host name and so forth, it means you are on the wrong host, and need to figure out where the mail ultimately gets delivered.
To actually try to deliver something and watch while Sendmail is doing it, try this:
$ sendmail -v username </dev/null username... Connecting to local... username... Sent
If there is an error, sendmail will be delivering a bounce message back to you using normal means.
-F fullname Set the full name of the sender.
-f name Sets the name of the "from" person (that is,
the sender of the mail).
-t Read message for recipients. To:, Cc:, and
Bcc: lines will be scanned for people to send
to. The Bcc: line will be deleted before
transmission. Any addresses in the argument
list will be suppressed.
To protect privacy, make
sure that messages always include a minimal
To: line, even if it is a dummy line with a
comment, such as
To: (names withheld)
-bp Print a summary of the mail queue.
-bv Verify names only; do not try to collect or
deliver a message. Verify mode is normally
used for validating users or mailing lists.
-d X Set debugging value to X.
-C file Use alternate configuration file.
-o xvalue Set option x to the specified value. Pro-
cessing Options are described below.
Processing Options There are a number of "random" options that can be set from a configuration file. Options are represented by single characters. The syntax of this line is:
Oovalue
This sets option o to be value. Depending on the option,
value may be
o a string
o an integer
o a boolean (with legal values t, T, f, or F;
the default is TRUE)
o a time interval
The options supported are:
aN If set, wait up to N minutes for an "@:@"
f Save Unix-style From lines at the front of
headers. Normally they are assumed redundant
and discarded.
l If there is an Errors-To: header, send error
messages to the addresses listed there. They
normally go to the envelope sender. Use of
this option causes sendmail to violate RFC
1123.
Ln Set the default log level to n. Defaults to
9.
-B type Indicate body type (7BIT or 8BITMIME).
-M id Attempt to deliver the queued message with
message-id id. This option is supported for
backward compatibility and the -qI option is
preferred.
-v Go into verbose mode. Alias expansions will
be announced, and so forth.
-X logfile Log all traffic in and out of sendmail in the
indicated logfile for debugging mailer prob-
lems. This produces a lot of data very
quickly and should be used sparingly.

It is doing DNS lookups to determine its hostname from the IP address. Modify /etc/nsswitch.conf to go to files before DNS for "hosts:" and make sure the /etc/hosts file contains the names and addresses that the DHCP server may assign it.

Unless of course you want cron messages.
Oh, and not so much of a security hole since it only accepts connections from localhost by default.

Funny, I'm getting cron messages on my system, and I'm not running Sendmail. I'm not expert enough to be able to tell you how they're getting to me, but they're there.

Do you have sendmail installed? You don't need to have a sendmail server running, but you do need the program available for mail to call on when you send stuff.
