QMAIL DOCUMENTATION9(TEST.deliver)

在QMAIL DOCUMENTATION中可以找到, 請按照自己的環境設定來測試

You can do several tests of qmail delivery without setting up qmail to
accept messages through SMTP or through /usr/lib/sendmail:

1. After you start qmail, look for a
          qmail: status: local 0/10 remote 0/20
  line in syslog. qmail-send always prints either ``cannot start'' or
  ``status''. (The big number is a splogger timestamp.)

2. Do a ps and look for the qmail daemons. There should be four of
  them, all idle: qmail-send, running as qmails; qmail-lspawn, running
  as root; qmail-rspawn, running as qmailr; and qmail-clean, running
  as qmailq. You will also see splogger, running as qmaill.

3. Local-local test: Send yourself an empty message. (Replace ``me''
  with your username. Make sure to include the ``to:'' colon.)
     % echo to: me | /var/qmail/bin/qmail-inject
  The message will show up immediately in your mailbox, and syslog
  will show something like this:
          qmail: new msg 53
          qmail: info msg 53: bytes 246 from qp 20345 uid 666
          qmail: starting delivery 1: msg 53 to local me@domain
          qmail: status: local 1/10 remote 0/20
          qmail: delivery 1: success: did_1+0+0/
          qmail: status: local 0/10 remote 0/20
          qmail: end msg 53
  (53 is an inode number; 20345 is a process ID; your numbers will
  probably be different.)

4. Local-error test: Send a message to a nonexistent local address.
     % echo to: nonexistent | /var/qmail/bin/qmail-inject
          qmail: new msg 53
          qmail: info msg 53: bytes 246 from qp 20351 uid 666
          qmail: starting delivery 2: msg 53 to local nonexistent@domain
          qmail: status: local 1/10 remote 0/20
          qmail: delivery 2: failure: No_such_address.__#5.1.1_/
          qmail: status: local 0/10 remote 0/20
          qmail: bounce msg 53 qp 20357
          qmail: end msg 53
          qmail: new msg 54
          qmail: info msg 54: bytes 743 from <> qp 20357 uid 666
          qmail: starting delivery 3: msg 54 to local me@domain
          qmail: status: local 1/10 remote 0/20
          qmail: delivery 3: success: did_1+0+0/
          qmail: status: local 0/10 remote 0/20
          qmail: end msg 54
  You will now have a bounce message in your mailbox.

5. Local-remote test: Send an empty message to your account on another
  machine.
     % echo to: me@wherever | /var/qmail/bin/qmail-inject
          qmail: new msg 53
          qmail: info msg 53: bytes 246 from qp 20372 uid 666
          qmail: starting delivery 4: msg 53 to remote me@wherever
          qmail: status: local 0/10 remote 1/20
          qmail: delivery 4: success: 1.2.3.4_accepted_message./...
          qmail: status: local 0/10 remote 0/20
          qmail: end msg 53
  There will be a pause between ``starting delivery'' and ``success'';
  SMTP is slow. Check that the message is in your mailbox on the other
  machine.

6. Local-postmaster test: Send mail to postmaster, any capitalization.
     % echo to: POSTmaster | /var/qmail/bin/qmail-inject
  Look for the message in the alias mailbox, normally ~alias/Mailbox.

7. Double-bounce test: Send a message with a completely bad envelope.
     % /var/qmail/bin/qmail-inject -f nonexistent
     To: unknownuser
     Subject: testing

     This is a test. This is only a test.
     %
  (Use end-of-file, not dot, to end the message.) Look for the double
  bounce in the alias mailbox.

8. Group membership test:
     % cat > ~me/.qmail-groups
     |groups >> MYGROUPS; exit 0
     % /var/qmail/bin/qmail-inject me-groups < /dev/null
     % cat ~me/MYGROUPS
  MYGROUPS will show your normal gid and nothing else. (Under Solaris,
  make sure to use /usr/ucb/groups; /usr/bin/groups is broken.)
