Actually, perhaps the easiest way around this and some other problems, such as keeping track of who is in the list, and allowing people to easily & rapidly remove themsleves, or change their addresses, is to use some maillist software. There used to be a plethora of systems around, but perhaps one of the easiest for beginners (both list members & list owners) is the web interface mail group systems - the most well known of which is Yahoo groups.

I don't know of any spam blockers that kill Yahoo groups consistently, and when they do, they usually get modified. If a list member is using something like mailwasher, it's easy to train it to let the yahoogroups stuff thru.

I run quite a few, and have set up many for others. You only have one address to worry about - the yahoo groups address. You can set it up as a send only 'newsletter' system, or as a discussion system

This solves your problem by ignoring it... :-)
