· Using TELVRIX

Mailboxes

Connecting, syncing, and managing IMAP/SMTP mailboxes — including app passwords, identities, and the vacation responder.

A mailbox in TELVRIX is a direct IMAP/SMTP connection to an email account you own. There is no OAuth and no provider lock-in: any server that speaks IMAP and SMTP works.

Connection requirements

• —IMAP host, port, and security mode (SSL/TLS, STARTTLS, or none) for reading mail.
• —SMTP host, port, and security mode for sending.
• —A username and password — for Gmail and Outlook this must be an app password.

Both connections are tested live before the mailbox is saved. A failed test blocks creation and shows the server error, so misconfiguration is caught at setup.

How credentials are stored

Mailbox passwords are encrypted with AES-256-GCM before they are written to the database. They are never logged, never cached in Redis, and not visible in any admin or support view. They are decrypted only at the moment a sync or send connection is opened.

How sync works

• —Folder discovery maps your provider folders, then messages sync incrementally.
• —With Redis configured by the operator, a background worker syncs continuously on a per-plan interval.
• —Without Redis, sync runs inline while you use the app.
• —Read/unread and star flags are written back to your provider over IMAP, and sent messages are appended to your Sent folder, so other clients stay consistent.

Identities and signatures

Each mailbox can have sending identities with display names and HTML signatures, edited with a rich-text editor. The correct from-address is selected automatically when you reply.

Vacation autoresponder

Each mailbox supports an out-of-office autoresponder with a date range and a reply-once-per-sender mode. Auto-replies send through your own SMTP server.

Mailbox limits

The number of active mailboxes in a workspace is set by its plan: 2 on Free, 10 on Pro, 25 on Business, and custom on Enterprise. The limit is enforced when connecting a new mailbox and on send.
