DumbMonit
Mailbox (IMAP)
An IMAP server greets, offers TLS and accepts a login, like a real mail client.
Product descriptions are in English, as in the product. The page labels follow your language.

How it connects
What you need
- Username / passwordSent once the connection is encrypted, never before.
No account needed.
Default port: 993
Setup steps: Monitor an IMAP server
In DumbMonit, enter the mail server, for example imap.example.com:1993 (port 993 with the default encryption).
Pick the encryption: TLS for port 993, STARTTLS for port 143, None for a server on your own network.
Optional: fill in a mailbox account, to check that the server still accepts logins (a refused password is not reported as an outage).
Heads-up. The check never opens a mailbox: a server that logs in but cannot read its storage answers perfectly here.
