stop mailing list emails being sent to spam
I'm part of some mailing lists (pfsense & mythtv lists) which a large number of them are being put into my spam folder.
Since they are from mailing lists, they do not appear as as typical email does.
An incoming email typically has the following info:
From: from the sender (so one of thousands of addresses)
To: Mailing-list email address
Subject: [<LIST NAME>] new updates available
Since the email address does not come from one sender, adding thousands of addresses (or hundreds of domains) to a white-list isn't a viable option.
I do have a filter than moves them based off subject line, to a new folder. However I do not see an option that would stop some of these emails going into spam.
How can i ensure that certain email does not get flagged as spam?
