eximstate is a pair of programs (a client and a server) which monitor the sizes of queues on Exim mail servers. The following data is stored by the server: total message on queue, how many of those are frozen, and how many of those are bounces.
Mailfeeder is a tool designed to inject a mailpack back into a MTA (mail server, ie, Sendmail, Postfix) using socket calls. Currently it is used in a variety of projects such as Inflex and Xamime to perform post-filtered queue injection or delivery.

Minimalist Queue Services
MQS (Minimalist Queue Services) is a minimalist queueing system in Free Software. The main purpose is to provide a set of basic methods in order to offer asynchronous messaging for program/application. Applications can use this type of services in order to store and retrieve message to dedicated queue in the queue services. This permits to avoid direct connection between applications and provides a simple asynchronous communication system.
This tool allows you to watch your mailqueue as it passes by, to drop some unwanted
messags from the queue, to look at the contents of the message, and lots of other
pfqueue is an effort to give postqueue/mailq/postsuper a console (ncurses) interface: it won't add any particular functionality to those provided with postfix itself, but will hopefully make them to use.
Putmail Queue provides a queuing system for putmail.py from the Putmail project. It allows you to compose your email messages offline, keep them in a queue, and send them all together later.
qgreylistrbl is an add-on for qmail. It is a further development of qgreylist by Jon Atkins. Connections from dialin lines, RBL-listed lines, and nodes without a reverse DNS entry get refused the first time with a temporary error message.
Qmail Remove removes messages containing a particular string from your Qmail queue. This is a useful thing to do in a number of situations. For instance, if you are hit with a spamming attack, you can temporarily instate a second Qmail installation (once the spam run is finished), allow it to take over mail receipt, and then use this tool to clean the offending mails out of the queue before switching over to the main Qmail installation once again.
qmHandle is a simple program which allows you to view and manage the qmail message queue. You can print queue statistics, like qmail-qstat, with color capabilities.
qmqtool is a qmail queue manipulation program geared towards the viewing and safe modification of the contents in a qmail queue.
qSheff is a wrapper for the qmail queue that scans email for viruses and spam. Infected messages are rejected before they reach the queue, so the server doesn't perform any job for them. After checking the message, it will wake the qmail queue.
sendqmailq is intended for home computers that run qmail as their MTA but do not have permanent connection to the Internet. The outbound emails are stored locally in a queue, and when the IP connection is brought up, sendqmailq sends them to the ISP's SMTP server. Unlike serialmail, sendqmail sends one single copy of an email to multiple recipients (instead of one copy each). Unlike serialmail, sendqmailq is slow, insecure and sucks at handling loads of emails.
