When sending out notifications to users via mail there happen all kinds of bounces. Often, the mail address does not exist anymore or the mailbox is full or they have some weird forwarding to another mailadress which results in a SPF failure. I've activated automated bounce handling and set up a dedicated mail box for that. This works and users with hard bounces get the state "invalid mail address" applied automatically. So far so good. But what comes next?
Some of those are older users that last visited ages ago. I could simply lock or delete their account. Others are regular users that visit frequently. Sure I could send them a PN, inform them about the issue and ask them to change their mail address. But this would be quite time consuming. Is there a way to force a user to change his mail address when he visits the forum next time? Or at least a way to notify them automatically about the issue?
