Hi

I see an option to block a sender’s email address on the filter page, but is there a facility to block emails sent to a specific local address?

I appreciate that’s a bit of a strange request however I have a rather unusual setup for protecting my email address.

I have an additional subdomain set up as follows:

*@gordon.mydomain.com forwards all email to gordon@mydomain.com

When I sign up to a service and hand out my email address (such as ebay for example) I would use the email address:
ebay@gordon.mydomain.com

If I start receiving a lot of spam to ebay@gordon.mydomain.com, firstly I know that it is ebay that has disclosed my email address and secondly I would then like to block any emails sent to ebay@gordon.mydomain.com

I can’t see a way to do this without delving into config files.

Any thoughts?

thanks
Gordon

Select Local network only in the email address: emails will be refused.

@GOB: block them where?
They are still forwarded to your gordon@mydomain.com account?
Is it an option to create a (blocking) filter in your mail program?

:bulb: Or maybe it would be better to not forward all mail from your subdomain but create a new forward mail address for each service you sign up and delete it if spam is detected?

thanks @filippo_carletti , that works perfectly.
Sending to a blocked address now issues an NDR:
“Recipient address rejected: Access denied”

Many thanks!
