Mail Systems

exim

commands

• see the queue:

mailq

• • or

exim -bp

the output shows the message queue giving useful information to work with it:

root@lingua:~# mailq
24h   379 1QC8cA-0001iy-B3 <ciaotest@server.company.n>
          hellobye@server.company.nl

• 1QC8cA-0001iy-B3

  message ID (corresponds to a filename)

  24h

  time msg spent in the queue

  379

  the size in bytes.

• find a queued message:

find /var/spool/ -name "1QC8cA-0001iy-B3*"

• to un-queue messages, I delete the files found by the find command (to rude maybe?)... it works

• flush the queue:

runq

• or

exim -q

• • flush queue forcing frozen messages to be sent

exim -qf 

• • flush queue forcing frozen/non-frozen messages to be sent

exim -qff
