Is there anything I can do? The only thing I can think of is to work
through the headers each time I get one of these bounce messages and
report it to the appropriate ISP. Trouble is, they're often quite
munged with no real case of who can be blamed.

Any comments and advice would be appreciated! Typical not-at-all
Cambridge related cam.misc posting, I'm afraid. :-)

Thanks,

Sam

I wouldn't worry about it. Just keep deleting all the mail. The same
thing happened to me. Although I got 100's of failed to be delivered
e-mails. And another 100 saying my e-mail had contained a virus and so
had been bounced. Spent a couple of weeks deleting them and it
stopped.
Over the weekend Bill Gates has come up with the great idea of
charging people each time an e-mail is returned to sender. To try and
stop spam. Not sure how it will work and if it will.
