I noticed a minor bug with your script that will prevent it from working
where whitespace preceeds the age of the message.

You are not specifying the variable to split, so it is using $_ and not
$in. IMHO, the easiest way to correct this is to omit $in completely and
to get both substitute (s///) and split to operate on $_ instead, i.e.:

> while (<QUEUE>) {
> s/^\s+//; # hack off leading spaces
> my ($age, $size, $id, $brackets, $from, $stuff1, $stuff2, $stuff3) = split
> /\s+/;


Alternatively, you could just change the script to use a match instead of
a substitute/split, which allows you to make sure that what you're getting
looks like a message ID, and gives you a warning if it fails to match what
you're expecting:

> while (<QUEUE>) {
>   if (m/^\s*(\S+)\s+\S+\s+(\w{6}-\w{6}-\w{2})/) {
>     my ($age, $id) = ($1, $2);
>     print "removing message: $id  age: $age\n";
>     system '/usr/exim/bin/exim', '-Mrm', $id;
>   } else {
>     warn "Invalid line $_";
>   }
> }


Hope this helps,

Regards,
