I am on a mailing list. Can I whitelist all messages sent to that mailing list?

Yes, you can whitelist a message by its "To" address, rather than the typical whitelisting by "From" address. This works because regardless of who is sending the message to the mailing list, the "To" address of that message should always be the mailing list address - for example, [e-mail]. Simply enter that mailing list address in the Management > Inbound Filtering > Whitelist page in the "Whitelist TO" area.
