Like everybody reading this Blog i use e-mail. My first e-mail account goes back about 20 years and as it was my name i had given it out a bit to much. Over the years i had a number of times had e-mails that had a virus in them. To this day i don't accept an e-mail if i don't know who it's from for that very reason. While i used windows i would always run a virus checker first. Due to the problems over potential virus attachments i ditched windows a long time ago for a safer operating system called Linux in fact Ubuntu Linux.
Anyway back to e-mails, Due to this problem i opened a number of e-mail accounts for various reasons. But recently Yahoo and Hotmail accounts i had gave me problems again and in a couple of days i found that on one Yahoo account i had over 157 spam e-mails. It was a constant problem that had been going on for to long and needed to be dealt with. My simple answer to this was to contact all those who had reason to e-mail me with new e-mail address's.
I have now deleted 5 e-mail address's from Yahoo and Hotmail. My original e-mail with Netscape was reasonably easy to delete. I also found that Hotmail was also easy to delete. Yahoo has been difficult to delete and i still have 2 to close it's no good just not logging in. E-mails from people you know will still arrive but what you need is for the e-mail to be sent back so that they know the e-mail couldn't be delivered.
My advice has always been to have a personal e-mail account for those closest to you then an e-mail for your extended family and then one to use for general use. That normally would be safe but you still can't be sure that those closer to you haven't had there e-mail accounts compromised.
One way problems arrive is when someone adds your e-mail to an e-mail they send to a group of friends. Each in the group also get your e-mail and it only takes one of them to have a virus of some kind on there machine and that's when problems start.
