Set up email in Thunderbird
Add a FiniteHost mailbox to Mozilla Thunderbird on Windows, Mac or Linux with manual configuration.
On this page
Thunderbird is a free mail app from Mozilla for Windows, Mac and Linux. It is a good choice if you want a desktop app that keeps a local copy of your mail, and it is also the easiest tool for copying mail between providers (see Move your email to FiniteHost). This guide adds priya@acme.in.
Before you start#
- The mailbox exists and you have its password (Email accounts).
- Thunderbird is installed from
thunderbird.net. - Keep these values ready:
Add the account#
- Open Thunderbird. On first start the account setup opens by itself. Otherwise open the menu (☰) → New → Existing Mail Account (or Account Settings → Account Actions → Add Mail Account).
- Enter Your full name (e.g. "Priya Sharma"), Email address
priya@acme.inand Password. Tick Remember password if this is your own computer. - Click Configure manually. (If you click Continue, Thunderbird tries to guess the settings. Its guess may be wrong; check every value against the table below before you accept it.)
- Fill in the Incoming server row: Protocol IMAP, Hostname
mail.finitehost.com, Port993, Connection security SSL/TLS, Authentication method Normal password, Usernamepriya@acme.in. - Fill in the Outgoing server row: Hostname
mail.finitehost.com, Port587, Connection security STARTTLS, Authentication method Normal password, Usernamepriya@acme.in. - Click Re-test. Thunderbird reports that the settings were found on the server.
- Click Done. Thunderbird downloads your folder list and the newest messages.
Recommended settings#
Open Account Settings (☰ → Account Settings) and select the account:
- Copies & Folders: "Place a copy in" → Other →
Sent on priya@acme.in. Drafts →Drafts on priya@acme.in. This keeps sent mail and drafts visible in webmail and on your phone. - Server Settings → When I delete a message: "Move it to this folder" → Trash.
- Server Settings → Check for new messages every 5 minutes is a sensible default. IMAP IDLE (push) is on by default, so new mail usually shows within seconds while Thunderbird is open.
- Junk Settings: FiniteHost already filters spam on the server. If you also want Thunderbird's own filter, set it to move junk to Junk on priya@acme.in.
Check that it works#
- Click Write, send a test message to another address you own.
- Check webmail's Sent folder for the message.
- Reply from the other address and watch it arrive in Thunderbird.
Troubleshooting#
| Problem | Fix |
|---|---|
| "Thunderbird failed to find the settings" | Expected for FiniteHost. Click Configure manually and enter the values. |
| "Login to server mail.finitehost.com failed" | Username must be the full address. Re-enter the password: ☰ → Settings → Privacy & Security → Saved Passwords, remove the old entry, then restart Thunderbird. |
| "Add Security Exception" dialog | The hostname is wrong. Use mail.finitehost.com. Do not add an exception. |
| Sending fails: "authentication method not supported" | Set the outgoing Authentication method to Normal password and Connection security to STARTTLS (587) or SSL/TLS (465). |
| Sent mail missing in webmail | Set Copies & Folders to the server's Sent folder. |
| Old messages are not shown | Thunderbird downloads folder by folder. Wait for it to finish, or right-click a folder → Properties → Repair Folder. |
