Sending to domain .edu

I sent my first campaign last night. This morning my inbox was full of “unsubcribe” messages, all from domain .edu (of which there are many on my subscriber list). Is this a known issue or “feature” of phpList?

@jimb This might be caused by anti-malware software at the receiver “following” links in the email. If that follows the unsubscribe link then this would be the result.

Look in config_extended.php for an explanation of UNSUBSCRIBE_JUMPOFF then add that to the config.php file with a value of 0 to disable being unsubscribed immediately.

@duncanc Thanks. I’ve changed the setting.
