- How to block “via” senders in Gmail 4 answers
I keep receiving spam mails from different senders using different domain names (e.g. email@example.com via utilityinbox.com).
I could create a filter to catch all mail from firstname.lastname@example.org, but I want to catch/filter all the mail sent via utilityinbox.com.
How could I achieve that?
