Your use of !~ should work properly here. However, I might suggest using ToCc instead of To. This will at least match mail that's Cc'ed to you... Of course, neither will match any mail that's Bcc'ed to you, including mailing list posts (ie: this list). So make sure you whitelist anyone who will send you Bcc'ed mail.
