erio b402c367d3 fix: add opportunistic STARTTLS to sendMailPlain for 587 port compatibility
smtp.SendMail automatically upgrades to STARTTLS when the server
supports it. Our replacement sendMailPlain skipped this, causing
credentials to be sent in plaintext on port 587. Add STARTTLS
negotiation before Auth to restore the original security behavior.
