Throughout my work as a sysadmin, managing qmail's queue seemed to be something that I often found myself doing, like, for instance when a server becomes deluged in spam from a Joe-job. At work we generally use qmHandle, an excellent piece of software. It, however, doesn't have quite all of the functions that we required, so I modifed qmHandle to give the -tX "string" and -M options that are seen below. qmHandle is licensed under the GPL. (See the documentation included in the tarball for more details).
As requested, I've updated the patch and applied it to version 1.2.0, appended a release tag of 'bovine', and updated the included documentation to reflect that it is a patched version. While version 1.2.0-bovine is mostly untested, you shouldn't have any problems with it, as no real code changes were made. In any case, version 1.1.1 is still available for download.
Here's the usage (obtained by running w/o any args):
