Hi I have been having problems with receiving a load of spam.

I have managed to deal with a lot of it with Rules, and Blocking Senders on the Webmail account (BTinternet) However a number of messages arrive with no e-mail address in the "From" box when I hover over it, so there is no address that I can block.

Very puzzled to know how an e-mail can have NO sender, and how to block these or divert them to a spam mailbox.

Any ideas please?

TIA
