Hermes Agent Email Gateway Requires Authentication-Results Header
The test shows that Hermes Agent's email integration depends on a specific email authentication header, which may cause setup issues with providers that omit it.
Reporting from 1 source: GIGAZINE.
GIGAZINE tested connecting Hermes Agent to email via IMAP and SMTP. After adding an allowed sender, replies still did not arrive. Logs showed the error 'no Authentication-Results header.' The email account used, Sakura's Mailbox, added ARC-Authentication-Results instead, which Hermes Agent does not read for sender authentication.
Hermes Agent's Gateway supports many messaging services, including Telegram, Discord, Slack, and Email. GIGAZINE connected an email account to test whether they could receive scheduled job results without opening the desktop app.
After entering IMAP and SMTP settings and adding their address to Allowed users, no reply came. Checking the gateway logs revealed the cause: the received email lacked an Authentication-Results header. The provider, Sakura's Mailbox, used ARC-Authentication-Results instead, which Hermes Agent does not reference. The authentication check failed silently.
