Thunderbird is a free e-mail client for Windows, macOS and Linux. Here is how to add your mailbox:
- Open Thunderbird and in the menu (three lines) choose New Account > Existing Email.
- Enter your name, full e-mail address and password and click Continue.
- Thunderbird looks up the settings automatically. Click Configure manually to check or enter the values.
- Incoming server: protocol IMAP, host name, port 993, connection security SSL/TLS, authentication Normal password.
- Outgoing server (SMTP): host name, port 465 with SSL/TLS (or 587 with STARTTLS), authentication Normal password.
- Username for both: full e-mail address. Click Re-test and then Done.
Which values apply depends on whether your mailbox belongs to a web hosting plan (cPanel) or to an e-mail package:

- Alternatively POP3: mail.yourdomain.ch, port 995, SSL/TLS
- Outgoing (SMTP): mail.yourdomain.ch, port 465 SSL/TLS or 587 STARTTLS
- Username: full e-mail address; enable SMTP authentication (same credentials)
E-mail package (E-Mail Postfach / E-Mail Business)
- Incoming (IMAP): mail.hoston.ch, port 993, SSL/TLS
