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.)
