Wildcards in message filters

[S Tyler]

So, I get a lot of junk mail with similar "from" senders, but they're just different enough that a standard name selection (like "Anderson Renewals") won't work.  This might appear as "Anderson Renewals" or "Anderson_Renewals".  This one actually shows up in about five different variations of the sender.

Is there a way to use a wildcard character so I don't have to list those five different ways within the message rule?

Also, why, when I mark something from LIDS as junk more than a hundred times does Postbox NOT see that and filter it for me?  There are others as well...not just from LIDS.
