How to add an unusual sender address to Outlook's junk mail facility?

Outlook 2003, XP.

Today I received a 2nd spam email which, when I tried to set a filter through the "Add sender to junk mail", popped up a message that the "email address or domain name is not valid". Obviously someone has a way to bypass normal Outlook capabilities.

Does anyone know how to overcome this?


I think you need to do similar to what Nicole suggested, but, just set the rule against any one who doesn't have a valid email address (or the sender is blank/empty). This way, since I assume your customers/clients/colleagues/business contacts etc, all send you email from a real domain, you're only removing those who you don't want.

  • +0 – I am accepting this - I tried it and a great deal of spam is now, at least, going to the junk folder. Thanks all. — Jan 23, 2013 at 21:23
