Setting up your e-mail
To set up your account in your e-mail software (Microsoft Outlook, Apple Mail, Thunderbird, your smartphone’s Mail app, etc.), use the following settings.
User name: simply use your full e-mail address. The former user+domain.ch format still works.
| Setting | Value | Port and security |
|---|---|---|
| E-mail address | name@your-domain.ch | |
| User name | name@your-domain.ch | |
| Incoming server IMAP (recommended) | mail.horus.ch | 993 (SSL/TLS) or 143 (STARTTLS) |
| Incoming server POP | mail.horus.ch | 995 (SSL/TLS) or 110 (STARTTLS) |
| Outgoing server SMTP | mail.horus.ch | 587 (STARTTLS), with authentication: same user name and password |
Choose IMAP if you read your e-mails on several devices: your messages and folders stay in sync everywhere. POP downloads the messages to a single device.

Frequently asked questions about e-mail
Which settings should I use to set up my e-mail?
Use your full e-mail address as the user name, and the server mail.horus.ch:
- IMAP (recommended): port 993 (SSL/TLS) or 143 (STARTTLS)
- POP: port 995 (SSL/TLS) or 110 (STARTTLS)
- SMTP (sending): port 587 (STARTTLS), with authentication
Full details and video tutorials are on the Support page.
IMAP or POP: which one should I choose?
IMAP, in most cases. Your messages stay on the server and are synchronised across all your devices (computer, smartphone, webmail). POP downloads messages to a single device: handy if you only want to keep them locally, but they will no longer appear elsewhere.
How can I read my e-mails in a browser?
With our webmail, from any computer or smartphone: rainloop.horus.ch. Log in with your full e-mail address and your usual password. The former webmail (Roundcube) is still available at webmail.horus.ch.
Does my old user name (user+domain.ch) still work?
Yes. You can now simply use your full e-mail address as your user name, but the former user+domain.ch format still works: there is no need to change a configuration that works.
My e-mails to Hotmail or Outlook are rejected (error 550 5.7.1). What should I do?
Since 5 November 2026, Microsoft has been rejecting some e-mails sent from domains without a DMARC record. We have added this record to all the domains we host. If one of your messages was rejected, simply send it again: Microsoft does not retry on its own. More details in our article (in French).
