Hi, Have the latest.
I was investigating email headers when I stumbled upon the following in an email from "firstname.lastname@example.org" to "email@example.com". A third party, firstname.lastname@example.org who I communicate with separately in a whole other thread, somehow got their email address into the SMTP header? They are not on the CC or TO field list in any way.
I know this isn’t MIAB specific (maybe) but can someone make sense out of this snippet of email header?
