I send out Newsletters etc. using a Windows application, Mach5 Mailer.
I have been using the companion application, Popmonger, to capture bounced emails.
The output from Popmonger is a list of the bounced email addresses.
We recently changed our email platform and the SSL settings are incompatible with Popmonger.
So I am looking for a Popmonger replacement.
The requirement is simply to create a list of the bounced email addresses.
I don't mind if the application runs on Windows or WordPress.
Our website runs on WordPress and Googling has shown a number of plugins that handle bounced email addresses.
Our subscriber list is maintained in MS Access, so I don't want to use a plugin that solely interacts with the WordPress User table.
