Maybe i am misunderstanding something, but SMTP is for sending mail.
Our plugin do mail bounce handling, which means it needs to connect to a mailbox that are receiving mail, like an IMAP or POP3 mailbox.
Hi @donaldhwong,
@kasperta is right about that, SMTP is used only for sending email not reading inbox. Now what I understand that you have aws SMTP server which you are using for sending mail through Mailpoet. If you want to handle bounced email, then you have to set a dedicated email address where mailpoet will send all bounced mail. You can set that email in mailpoet settings page under Advanced tab where you will see a option name Bounce email address .
After setting up that address you have to use that email address to connect and handle bounced using this plugin.
I hope that the problem was resolved in the new version.
