I'm quite sure I'm not the first guy who asks this but I haven't found any response with my bro' Google.
Basically, we have a registration page and we'd like to monitor all the e-mails that are sent via our server, so that if an e-mail is refused by a third-party server we can manually see that the user e-mail address does not exist or that its provider rejects our e-mails.
Of course we have the logs but it's quite complicated when you have a registration every 5 seconds.
So I'm looking for something that is web based (a simple PHP interface ? or even a JAVA servlet) that would list all e-mails sent and whether they have been received, rejected etc.
This would allow a support representative to manually monitor e-mails.
