Webmail

Webmail lets you read and send mail in the browser. Sign in with the full email address and the mailbox password.

Server webmail

On the Email page, the Web mail section turns webmail on or off for the whole machine. It is a small separate Go program that listens on a port next to the panel’s port and shares the panel’s certificate.

• The program exits after 15 minutes of nobody using it and restarts when someone opens it, so it uses no RAM while idle.
• The first time, the panel downloads the program and verifies its checksum before installing.
• The panel adds a firewall rule for the webmail port when the panel firewall is on.
• The panel must be installed on this machine, because webmail uses its port and certificate.

Webmail on a website’s domain

The Webmail on this domain card in the website’s Overview tab turns on webmail at the website’s own /webmail/, with no extra domain or certificate. It also works with extra domains.

Requirements:

• The mail server and webmail are turned on in the Email page.
• The website has SSL, because passwords must not be typed over a plain connection.
• If the website uses a custom vHost, the panel cannot add it for you. Add the /webmail/ block to the vHost by hand.

Caution

Webmail shares its origin with the website. If the website has a code-execution vulnerability, someone with webmail open there could have their mail read. Turn it on only for websites you trust.

Language

Webmail is a separate program, so it does not yet follow the panel’s language switch.
