Dear users!
CleanTalk has expanded the functions of personal blacklists. We’ve added an ability to filter email addresses by a mask.
Symbol asterisk “*” means any set of characters.
Examples:
name*@example.com (all e-mail addresses with any set of characters after “name” will be blocked).
*aa**@ex*****.com (all e-mail addresses with any set of characters before “aa44” will be blocked).
*kkk*vvv*@example.com (all e-mail addresses with any set of characters before “kkk”, before “vvv” and after “vvv” will be blocked).
And so on, you can use any combinations of characters and asterisks to make a mask.
Instructions how to use the personal blacklists can be found here https://cleantalk.org/help/blacklist-usage
