Re: none for me...
My Plusnet email account gets no mail whatsoever, other than one per month from PN telling me they're going to take some money out of my bank account (unless I've raised a ticket and then I get a few more).
Now I don't know whether it's relevant but I'me one of the old Force 9 brigade, so my email account is email@example.com.
The secondary email PN has is my work address, which also gets copies of all PN mail. However we have a cast-iron spam filter here, so if I was getting the PN-related spam I wouldn't know.
As an aside, each day our organisation rejects 90% of all mail arriving at our gateway...approximately 900 mails.
