Blocking Spammer Who Uses Variations Of The Same E-mail Address.

Is it possible to block a spammer who uses numerous variations of the same e-mail address?

I use webmail for my e-mail (live.ca).
(aka Hotmail and Outlook)

I've tried creating "rules", but either I'm doing it wrong, or it's not possible to block this type of e-mail address?

Highlighted in bold is the part of the address that is always used.
.usesubscriber.online

one example: pfCzfGLdZr@ADZOOMA.Vo8.usesubscriber.online

I also report the spam to the webmail service and block each individual e-mail. Of course, I think it just causes me to receive more.

 

The sure way to see and be able to block the sender's IP address is to use a good email client such as Thunderbird. I don't think it's possible in Outlook.com. Blocking the IP is effective unless the sender's ISP gives them a new IP for each session, as mine does. Blocking a spammer's email address will probably be ineffective as the email address can be spoofed by the sender.

 

Thank you.

 

FWIW...
Email addresses, Domain names and IPs can be blocked in Outlook Mail settings.

Click the email > click the 3 dots > scroll down > click View message source.

 

Thank you!
Ok, when I click on View message source, there's a whole lotta info on there. What do I do next?

 

Look for this:
Authentication-Results: spf=pass (sender IP is 208.**.***.**)

 

Thank you.

I found a line slightly different from your example.
It says, "softfail" instead of "pass".

Is that ok to use?

Authentication-Results: spf=softfail (sender IP is 44.***.**.***)

 

Yes.
