Как подключается
Что понадобится

Учётная запись не нужна.
Порт по умолчанию: 587
Шаги настройки: 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.
Обратите внимание. An accepted session does not prove mail leaves: watch the relay's queues for that.
