MailBounce for Mac

From Smart Mail Solutions, Inc.:

MailBounce allows list owners to manage large volumes of bounces from mailing lists. It recognizes, categorizes, sorts, tracks, and removes repeatedly bouncing addresses from mailing lists. MailBounce puts the list owner in control of which addresses are removed, by allowing the list owner to select the removal thresholds.

MailBounce is distributed as a freeware product ("MailBounce Lite"), and can be upgraded to the full-featured version ("MailBounce Pro") for a fee; see http://www.mailbounce.com/mailbounce_pro.html for more information.

Note: This product was formerly known as "SmartBounce."
