The key features of qmHandle are:

• Freeware and open source, under the GNU General Public License;
• More information provided when reading queue contents compared to qmail-qread
• You can print queue statistics, like qmail-qstat, with color capabilities;
• You can view a message in the queue;
• You can remove one or more messages from the queue based on a criterion or use multiple delete requests each having its own criterion;
• Written in Perl, and therefore easily customizable and truly multiplatform.

The software will work on every Unix platform with Perl installed and qmail installed.
