How to set up your email account (IMAP / POP3)
Server names, ports, and SSL settings to connect CR Servers mailbox accounts in desktop or mobile email apps.
Use these settings after you create a mailbox in your hosting control panel.
Recommended: IMAP
IMAP keeps mail on the server so you can read it from multiple devices.
| Setting | Value |
|---|---|
| Incoming server | mail.crservers.com (or mail.YOURDOMAIN.com, see below) |
| Incoming port | 993 with SSL/TLS |
| Outgoing (SMTP) server | Same as incoming |
| Outgoing port | 465 with SSL, or 587 with STARTTLS |
| Username | Full email address (you@YOURDOMAIN.com) |
| Password | Mailbox password |
| Outgoing authentication | Required: same username and password as incoming |
The password is the mailbox password, not your hosting control panel password.
Use mail.crservers.com for your CR Servers mailbox. You may use mail.YOURDOMAIN.com instead if CR Servers has confirmed that this hostname points to our mail service and is covered by the certificate our mail server presents for it. Your website may be hosted elsewhere. Never accept certificate warnings or turn off certificate verification.
Alternative: POP3
POP3 downloads mail to one device and may remove it from the server depending on client settings. Prefer IMAP unless you have a specific reason to use POP3.
| Setting | Value |
|---|---|
| Incoming port | 995 with SSL/TLS |
| SMTP | Same as IMAP above |
iPhone and iPad
- Settings → Apps → Mail → Mail Accounts → your account → Account.
- Under Outgoing Mail Server, tap SMTP, then the Primary Server (it may show a different name than
mail.crservers.com). - Set Host Name
mail.crservers.com, User Name your full email address, Password the mailbox password, Use SSL on, Authentication Password, Server Port465. - These fields are required for CR Servers even if iOS labels them optional.
Test it
Send a message to an address outside your domain (for example a personal Gmail) and reply to it. If both arrive, sending and receiving work.
Tips
- Keep SSL/TLS on. Never send passwords in plain text.
- If an older email app still shows a certificate warning with
mail.crservers.com, contact support: it may need the server name we give you. Don't turn off SSL/TLS. - MX records only affect mail arriving at your domain. You don't need to wait for MX changes to test signing in to
mail.crservers.com. - Spam filtering and authentication (SPF, DKIM, DMARC) improve deliverability — see related articles.
