Search with an envelope to address
I have a domain so any email I use comprises of name@mydomain.co.uk
In the past I have given an email address to some dodgy enterprises such as Abbey National plc, and so I get loads of spam to abbey@mydomain.co.uk
It is an utter pain that many spammers use a throw away or random To: address but because the envelope email is abbey@mydomain.co.uk I get to receive it and there is no easy way of searching a folder to find matches to "envelope to".
Similarly it seems impossible to construct filters for an "envelope to" address.
Any ideas?
