Hi Sheila M
I need to find a way to extract lists of emails from Junk mail folder and add them en masse to blocked senders, without having to add them to my blocked senders one by one.
I have had the same email address for too long to change it, but I receive huge amounts of junk mail. I have so far barred nearly 2000 senders and have 1100 sitting in my junk folder form the last week. I barred them one by one, using RULES function...I simply cannot keep doing this.
I have MacBook Pro running Mavericks, plus iPad plus iPhone 5.
The problem is aggravated by the fact that Apple has a weakness in Mail: I may bar thousands of senders on my Mac, but the filter does not sync the barred addresses to my iPad or iPhone, so if I use Mail on either, I get many thousands of emails at once and have to mark them one by one to delete. It's ridiculous.
To solve this problem, I have decided to do is block all the senders in webmail.
However I still have the same problem with extracting multiple addresses from my junk mail folder in order to copy them into blocked senders list.
Genius Bar said it can't be done. I think they're wrong. There simply as to be (a) a location on my Mac where I can find a list of all those I have already barred; (b) a way to extract email addresses from groups of received mail.
I'd be grateful for some advice, please.
