Spam Filters & Domains

#1

When I block a domain using the Spam filter in DA dashboard, does it also block all subdomains?

Some spammers are sending via subdomain, and Im not sure which one to block.
I have been blocking both:

mail.spammer.com
spammer.com

Spammers are getting on my nerves!
I get at least 5 emails a day.
Same effing people using new domains every couple of weeks.
Drives me NUTS!

Kind Regards,

Nathan

It does not block all sub domains. You’d have to do those individually. Use the envelope from header as your guide, that’s what it works from.
