Searching the queue with exiqgrep.
Exim includes a utility that is quite nice for grepping through the queue, called exiqgrep. This is much better than doing things the hard way, like piping `exim -bp` into awk, grep, cut, or `wc -l`. Don't make life harder than it already is.
First, various flags that control what messages are matched. These can be combined to come up with a very particular search.
Use -f to search the queue for messages from a specific sender:
exiqgrep -f [luser]@domain
Use -r to search the queue for messages for a specific recipient/domain:
root@localhost# exiqgrep -r [luser]@domain
Use -o to print messages older than the specified number of seconds. For example, messages older than 1 day:
root@localhost# exiqgrep -o 86400 [...]
Use -y to print messages that are younger than the specified number of seconds. For example, messages less than an hour old:
root@localhost# exiqgrep -y 3600 [...]
Use -s to match the size of a message with a regex. For example, 700-799 bytes:
root@localhost# exiqgrep -s '^7..$' [...]
Use -z to match only frozen messages, or -x to match only unfrozen messages. There are also a few flags that control the display of the output. Use -i to print just the message-id as a result of one of the above two searches:
root@localhost# exiqgrep -i [ -r | -f ] ...
Use -c to print a count of messages matching one of the above searches:
root@localhost# exiqgrep -c ...
Print just the message-id of the entire queue:
root@localhost# exiqgrep -i
