I have a group of incoming email addresses that need to be moved to a single directory in the mail tree. The idea is that incoming email from Ann, Bob, Cathy, Doug, Ed or Francis, should be put in the IMAP directory named, say, "Tree Project".
Individual rules work fine, of course, but being a lazy man I wondered if there was way to set up a single filter for it. None of these people have SME user accounts.
I believe the mail sort contrib uses regex for the filter parsing, so I tried using pipes between the incoming addresses. I found that pipes are not allowed. I also tried a comma delimited string but that appears to function like "and".
How might I set up an "or" filter?
Perhaps a better question is "What flavor of regex is used in SME/mail sort?"
