Setting up a desktop or phone mail client to talk to your Noxity mailbox uses standard IMAP/SMTP settings. cPanel can hand you the exact values, and most modern clients auto-discover them from your email address alone.

​
The settings

Two protocols matter:
  • IMAP for receiving mail (recommended; keeps mail on the server, syncs across devices)
  • SMTP for sending mail
POP3 also works but isn’t recommended; it downloads mail and removes it from the server, which loses the cross-device sync that makes modern email work.
SettingValue
IMAP servermail.yourdomain.com (or your server hostname directly)
IMAP port993 with SSL/TLS
SMTP servermail.yourdomain.com
SMTP port465 with SSL/TLS, or 587 with STARTTLS
UsernameFull email address (you@yourdomain.com)
PasswordThe mailbox password
AuthenticationRequired (same credentials for IMAP and SMTP)
If mail.yourdomain.com doesn’t resolve yet (DNS issue), substitute your server’s hostname directly. Look it up in cPanel home under General Information → Shared IP Address or use the actual server hostname (*.web.systeminterface.net).

​
Get the exact values from cPanel

cPanel can also give you a config file or app-specific instructions:
1

Open Email Accounts

cPanel home → Email → Email Accounts.
2

Click Connect Devices

Next to the mailbox row.
Connect Devices output with auto-config scripts and manual settings
3

Pick your client

cPanel offers downloadable auto-config scripts for Outlook, Apple Mail, Thunderbird, and others, plus manual settings for everything else.

​
Set up by client

Just enter your full email address and password. Apple Mail auto-discovers IMAP/SMTP from mail.yourdomain.com.If auto-discovery fails (DNS not propagated yet), use Other Mail Account and paste the values from the table above manually.
File → Add Account → enter the full email address. Outlook attempts auto-discovery; if it fails, click Advanced options → Let me set up my account manually, pick IMAP, and enter the table values.For incoming server: mail.yourdomain.com, port 993, SSL/TLS. For outgoing server: mail.yourdomain.com, port 465, SSL/TLS, authentication required.
File → New → Existing Mail Account → enter your name, email, and password. Thunderbird probes for the right ports automatically and offers IMAP or POP3. Pick IMAP.Manual config available under Manual Config if auto-detection picks the wrong settings.
Settings → Mail → Add Account → Other → Add Mail Account. Fill in name, email, password, description.If auto-discovery fails (the iPhone tries mail.yourdomain.com automatically), tap manual setup. Pick IMAP. Use the values from the table above; the same mail.yourdomain.com for both incoming and outgoing.
On most Android mail apps: enter the email address and password. The app auto-tries mail.yourdomain.com on standard ports.If it fails, the manual configuration option asks for IMAP/SMTP servers, ports, and authentication. Same values as above.
No setup needed. Visit https://webmail.yourdomain.com (or https://yourdomain.com/webmail) and log in with the email address and password. Roundcube opens.Use webmail for occasional access without configuring a desktop client.

​
Common pitfalls

The standard mail subdomain only works if your DNS includes a record for it. Most cPanel accounts get one automatically, but custom DNS setups (e.g. Cloudflare-managed) may have skipped it. Either add an A record for mail.yourdomain.com pointing at your server, or use the server hostname directly (*.web.systeminterface.net:993).
Always check that My outgoing server requires authentication is on, and that the credentials are the same as IMAP. Some clients default to “no auth on SMTP” which fails.
ISPs and firewalls often block port 25 outbound. Always use 465 (SSL) or 587 (STARTTLS) for sending. If 587 fails, try 465.
If you see an SSL certificate warning when connecting, your domain probably doesn’t have AutoSSL set up for mail.yourdomain.com. Check AutoSSL in cPanel and ensure mail subdomain coverage. As a workaround, use the server’s actual hostname (*.web.systeminterface.net) which always has a valid certificate.
SMTP-specific. Verify you’re using port 465 with SSL or 587 with STARTTLS, with authentication on. Test by sending to a different external address (not yourself) so the failure is more visible.

Tips

  • Use IMAP, not POP3. IMAP keeps mail on the server and syncs to all your devices. POP3 downloads and removes, breaking multi-device.
  • One password, two services. IMAP and SMTP use the same email + password. If one works, the other should too. If only one works, the issue is server/port settings, not credentials.
  • Switching from another host. If you migrated from another mail host, your client probably has the old server settings cached. Delete and re-add the account from scratch rather than trying to update settings in place.
