As I have just posted in another similar thread, I am getting more than that on a daily basis now. The latest batch are now coming from the following address format:
*@*.onmicrosoft.com
Unfortunately, because there is a random string of characters after the @ symbol, blocking the domain doesn't help as it's different every time. So I've had to set up yet another new filter to block anything coming from email addresses ending onmicrosoft.com.
I appreciate that this is not an easy problem to solve, but it is becoming increasingly tiresome having to set up my own filters as BT's are just not up to the job at the moment.
Interestingly, if I forget to check my webmail before opening my email client (Outlook), more often than not, these ones that are getting though BT's spam filters ARE being recognised by Outlook and getting diverted to the spam folder in the email client.
So perhaps BT needs to get some advice from Microsoft as whatever rules they are applying within Outlook are currently more effective than BT's own ones.
