Mail “from you” that you never sent?
That can be spoofing (forged From) or a real compromised mailbox. First check the public domain defenses — no login needed.
Two different problems
- Spoofed sender — often without access to your account; mainly fixed with DMARC.
- Hacked mailbox — stolen password/session; then MFA, reset, inbox rules, audit — DNS alone is not enough.
