I'm currently seeing a flood of shotgun spam to swathes of hundreds of obviously harvested addresses, not even bcc'd. It lends itself to what seems a straightforward policy of rejecting anything with more than, say, fifty addressees.

I'm thinking something like this:


if /^To:/
...
/(@[^@]){50,}/          REJECT
...
endif


Have I missed anything obvious?
