How GTM Inboxes uses this term
GTM records redacted smtp_smoke_test agent logs, updates SMTP readiness, and alerts on repeated alertable failures without returning raw passwords or recipient addresses.
What message accepted means
A message-accepted result means the SMTP server accepted the controlled test message. It does not prove the message landed in the inbox, avoided spam, or reached any prospect mailbox.
Why the output is redacted
Smoke-test logs may touch credential and recipient workflows. GTM stores stage, domain, response code, sanitized error, and next action, never plaintext SMTP passwords or raw recipient addresses.
