Searching the queue

Exim includes a utility that is quite nice for grepping through the queue, called exiqgrep. Learn it. Know it. Live it. If you’re not using this, and if you’re not familiar with the various flags it uses, you’re probably doing things the hard way, like piping `exim -bp` into awk, grep, cut, or `wc -l`.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Search the queue for messages from a specific sender:

Quote:
# exiqgrep -f [luser]@domain
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Search the queue for messages for a specific recipient/domain:
Quote:
# exiqgrep -r [luser]@domain
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Print just the message-id as a result of one of the above two searches:
Quote:
# exiqgrep -i [ -r | -f ] …
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Print a count of messages matching one of the above searches:
Quote:
# exiqgrep -c [ -r | -f ] …
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Print just the message-id of the entire queue:
Quote:
# exiqgrep -i
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Managing the queue, Start a queue run:
Quote:
# exim -q -v
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Start a queue run for just local deliveries:
Quote:
# exim -ql -v
