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.

This is what I needed without realizing I needed it. I don’t think I ever really grasped what “JUMPOFF” was. I recently lost a few subscribers immediately after sending to my pen-name newsletter, which is set to unsubscribe immediately but also send a confirmation email (which has resulted in a spam complaint in the past). One of the people I lost replied to that confirmation email and asked why he was being unsubscribed, so clearly it was the receiving mail system that “clicked” the link.

Given the potential for spam complaints from a confirmation message and the potential for unintended unsub activity, I’m going to make sure my real-name and pen-name newsletters are set to not unsub immediately (and also to not send a confirmation). I think this is a safer configuration, but I think the opposite is the default (unless I chose it at some point and then forgot).
