Posting a question on behalf of a friend who'd asked me for help?
As some of you probably know (I didn't until I looked into this), gmail email addresses ignore ".". So, if your address is say, snipped-for-privacy@gmail.com, then all mail sent to johnsmith, even with as many "." inserted within it (e.g. snipped-for-privacy@gmail.com, snipped-for-privacy@gmail.com) will arrive at your mailbox - you basically own johnsmith and all its variations that include ".".
His email address is of the type " snipped-for-privacy@gmail.com".
Recently he's started receiving emails addressed to snipped-for-privacy@gmail.com, snipped-for-privacy@gmail.com, and a few similar ones - not a flood, just a few here and there. Problem is that the emails look 100% legitimate. They were sent by what appears to be real people/organisations to real people, and are about real issues. For example, from a local university department, to a student, discussing registering for a course for the net term, or from Netflix to a customer with the usual upcoming new movies reminder. Nothing to suggest anything wrong. I had a look at the headers of a couple, and they all look legitimate too.
He is not too bothered about receiving a bit junk mail, but is concerned that perhaps if he can see their emails than those people have access/receive his emails too.
I am a bit confused? Any thoughts?
My advise to him is to change his password, and try to contact one or two of the senders to see if anything makes sense (but I am aware that data protection will probably be an issue and they will refuse to discuss).
