In theory one can set any domain to "from" field, what about actual servers that sent the spam? How many of those spam emails have unsubscribe and/or complaint headers?
- avian 4y agoIn theory the domain you set the "From:" field to will have DMARC, DKIM and SPF set up and in theory the recipient that implements those protocols will discard your mail as sent from an unauthorized server.
- chaoz_ 4y agoAnd if you don't have at least DKIM + SPF, then you will not even reach any public provider's inbox.
- Ensorceled 4y agoThe spam emails pretty much ALL have unsubcribe headers now. I mean, they are all WORSE than useless since they are sending signal back to spammers, but Gmail is asking me to [Unsubscribe and Report Spam] anyway.
