Here are a couple of web pages that list many such applications. Several do
use MySQL (or support MySQL) as there backend database server.
http://linas.org/linux/pm.html
http://www.iac.honeywell.com/Pub/Tech/CM/PMTools.html
Here are a couple that I didn't see mentioned on either of the above lists.
SupportWizard
http://www.supportwizard.com/
"Further strengthening their relationship, SupportWizard and MySQL - the
world's favourite Linux database, announce a joint marketing and sales
relationship."
WebTTS

(it doesn't look like this one supports e-mail yet)
I know there are others, but I lost my bookmarks. :(
Hope this helps.
