Roundcube's settings let you make webmail feel like your own email app: a professional signature, the right name on outgoing mail, your time zone and the reading layout you prefer. Settings are saved per mailbox on the server, so they apply on every computer you log in from.
Before you start
- Log in to Roundcube at
https://yourdomain.com:2096. New to webmail? Read how to use Roundcube first.
Add an email signature
- Click Settings (gear icon) → Identities.
- Click your address in the list.
- In Display Name, enter the name recipients should see, e.g.
Sara Khan | Example Ltd. - In Signature, type your signature. Click the HTML icon in the toolbar to add bold text, links or a small logo hosted on your website.
- Tick HTML signature if you used formatting, then click Save.
Then go to Settings → Preferences → Composing Messages and choose:
- Automatically add signature: always, or only for new messages.
- When replying: place the signature below the quoted message or above the quote.
- Remove previous signature when replying: avoids repeated signatures in long threads.
Tip: Keep the signature short, avoid large images and include a plain-text phone and website. Heavy HTML signatures increase the chance of spam filtering.
Create extra identities
An identity is a sender profile. Use it to send from a forwarder or alias that delivers into this mailbox, or to set a different reply address.
- In Settings → Identities, click + Create.
- Fill in Display Name and Email, for example
sales@example.com. - Optional: set Reply-To and Bcc, and its own signature.
- Click Save. When composing, pick the identity from the From drop-down.
- Signature not showing: it belongs to one identity; check the identity selected in From, and the "Automatically add signature" option.
- Images in signature broken for recipients: the image must be a public
https://URL, not a pasted file. - Settings reset: settings are per address; you may be logged in to a different mailbox.
Only use addresses on your own domain. Sending as an address from another provider (e.g. Gmail) fails SPF and DMARC checks and lands in spam.

Change the mailbox password
Roundcube on cPanel has a Password section in Settings when enabled by the server. Otherwise the account owner changes it in cPanel → Email → Email Accounts → Manage → Security. Remember to update the password on your phone and desktop apps afterwards.
