Roundcube settings: signature, identities, display and composing options

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

1. Click Settings (gear icon) → Identities.
2. Click your address in the list.
3. In Display Name, enter the name recipients should see, e.g. Sara Khan | Example Ltd.
4. 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.
5. 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.

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.

1. In Settings → Identities, click + Create.
2. Fill in Display Name and Email, for example sales@example.com.
3. Optional: set Reply-To and Bcc, and its own signature.
4. Click Save. When composing, pick the identity from the From drop-down.

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.

Display and language preferences

Setting	Where
Language, time zone, date format	Settings → Preferences → User Interface
Light or dark skin (Elastic)	User Interface → Interface skin; dark mode follows the toggle at the bottom-left
List or threaded view, layout	Mailbox View → Layout (widescreen, desktop, list)
Show remote images	Displaying Messages → Allow remote resources: from my contacts only (safer)
Plain text or HTML by default	Composing Messages → Compose HTML messages
Request read receipts	Composing Messages → Always request a return receipt
Empty Trash on logout	Server Settings → Clear Trash on Log Out

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.

Troubleshooting

• 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.
