You've discovered a spammers trick.. they use the unsubscribe feature to build up their email databases.
The moral here is to only use the unsubscribe feature on emails from legit companies.
So, you can't stop the emails coming in but you can filter them.
Log into your email using the web interface. (this may be what you normally do; on the other hand if you're used to using a desktop client such as Outlook, you'll have to figure out how to log in using the web)
Once logged in , there should be some spam filtering options - sometimes you have to dig through the menus to find them. Make sure spam filtering is on, & set to medium if possible.
If you normally use a desktop client, you can also make some settings in that software to filter spam. You can for example set it to send items from certain senders straight to the bin, or check the text in the email for certain words.
Hope this helps
I was receiving lot of junk mail and decided to use unsubscribe option to reduce the spams. Ho Ho Ho, instead of reduced spam mail, I started receiving hundreds of unwated mails in my mail box.
I suppose that the unsubscribe option is not really as such, it's a subscribe option really. Now, how do I get my mail box, free from all these spams ?
