Tribulant Newsletter offer two methods of bounce email management: email piping and POP/IMAP mailbox. If you use the POP/IMAP method, you can simply specify an address that will receive the bounced email and the plugin will check that address to see if there were any bounces. And then the plugin will perform the necessary clean up.
MailPress provides extensive configurations for managing bounces. Obviously, you can specify the POP3 server and email that will receive the bounces. And you can set the maximum number of bounces before an email address is deactivated. But like many things in MailPress, this too can feel a bit technical. Luckily, there is comprehensive documentation for bounced email handling in MailPress.
[GWA] Autoresponder is able to track bounces and remove them from your mailing list. It's up to you how many times a message bounces before the recipient is removed from your list.
In the settings page of e-Newsletter, there's a dedicated tab to "Bounce Settings". There, you can configure the email address that will handle bounces. However, I can't find where you'd set the maximum number of bounces before a subscriber is deactivated.
