There are many times when a mail queue may become filled with what is essentially junk mail, At extreme levels, this can cause high load & delayed mail delivery.
You can use a variation of the following command via a shell prompt to delete only these junk messages from the mail queue.

grep -lR KEYWORD /var/spool/exim/input/* | xargs rm -f

(This will purge the mail queue of any messages that contain KEYWORD.
Any messages deleted in this manner are IRRETRIEVABLE (aka: Gone for good)
Is this dangerous? You bet it CAN be.)

Let's look at an example:-

Imagine a case in which users are abusing a bad FormMail.pl installation on server.fastservers.net. Almost all of these messages will contain the username "nobody@server.fastservers.net". We want to delete ALL of these messages, so we would insert "nobody@server.fastservers.net" in place of "KEYWORD" in the command above.
This will delete all messages in the exim queue that contain the keyword "nobody@server.fastservers.net".

Grep does regular expressions, This means you can catch tricky spammers with a little mind power.

 For example:-

grep -lRP Vz*Az*Lz*Iz*Uz*M /var/spool/exim/input/* | xargs rm -f

This command will delete any message containing the letters V, A, L, I, U, M, in that order, And with 0 or more "z" characters between them. A few of the keywords it will match are listed:
VALIUM
VzALIUM
VAzLIzUzM
VALzIUM
VzALzIUM
You get the idea.
