Mail relay (SMTP)
A mail server greets, offers STARTTLS and accepts a login, like a real client.

Comment il se connecte
Ce qu'il faut
- Username / passwordSent once the connection is encrypted, never before.
Aucun compte nécessaire.
Port par défaut: 587
Étapes de mise en place: Monitor a mail relay
In DumbMonit, enter the mail server, for example smtp.example.com:2525 (the usual port for the encryption by default).
Pick the encryption: STARTTLS for port 587, TLS for port 465, None for a relay on your own network on port 25.
Optional: fill in an account, to check that the relay still accepts it (a refused password is not reported as an outage).
Optional: name an Expected extension, such as STARTTLS, to be warned when the relay stops advertising it.
À savoir. An accepted session does not prove mail leaves: watch the relay's queues for that.
