Thanks Jim,

I tried the above code and i noticed you had the substr co ordinates wrong.

i changed it to:

$mday = substr("$ARGV[0]", 6, 2);
$mon = substr("$ARGV[0]", 4 ,2);
$year = substr("$ARGV[0]", 0 ,4);
$hour = substr("$ARGV[0]", 8 ,2);
$min = substr("$ARGV[0]", 10 ,2);
$sec = substr("$ARGV[0]", 12 ,2);

however whenever i run the script i get:

0 minus 0 = 0 which is less than three days

the current date is: 20080318110043 and the test date is the same you used. Smilie

NAME

       mailq - prints the mail queue

SYNOPSIS

DESCRIPTION

       prints a summary of the mail messages queued for future delivery.

       The  first line printed for each message shows the internal identifier used on this host for the message, the size of the message in bytes,
       the date and time the message was accepted into the queue, and the envelope sender of the message.  The second line shows the error message
       that  caused  this  message  to be retained in the queue; it will not be present if the message is being processed for the first time.  The
       status characters are:

	      to indicate that the job is being processed

	      to indicate that the load is too high to process the job

	      to indicate that the job is too new in the queue to process.

       The output lines that follow the second line show the message recipients, one per line.

       is identical to

   Options
       The supported options are:

       Show the mail submission queue specified in the
		       file instead of the MTA queue specified in the file.

       Show the lost items in the mail queue instead of normal queue items.

       Show the quarantined items in the mail queue instead
		       of the normal queue items.

       Limit processed jobs to those containing
		       substr as a substring of the queue ID or not when is specified.

       Limit processed jobs to quarantined jobs containing
		       substr as a substring of the quarantine reason or not when is specified.

       Limit processed jobs to those containing
		       substr as a substring of one of the recipients or not when is specified.

       Limit processed jobs to those containing
		       substr as a substring of the sender or not when is specified.

       Print verbose information.
		       This adds the priority of the message and a single character indicator or blank) indicating whether a warning  message  has
		       been  sent on the first line of the message.  In addition, extra lines may be intermixed with the recipients indicating the
		       `controlling user' information.	This shows who owns the programs that are executed on behalf of this message and the  name
		       of the alias this command expanded from, if any.
