Mail Server Setup in cPanel

This document explains how to properly set up email accounts such as info@yourdomain.com or contact@yourdomain.com when:

The domain is registered at Guzel.net
DNS is managed through Guzel.net DirectAdmin panel
Hosting and Mail server are on FastComet (cPanel)

Creating Email Accounts in FastComet cPanel

Log in to FastComet cPanel.
Go to Email Accounts.
Create a new account (e.g., info@yourdomain.com) with a secure password.
You can access this inbox from cPanel directly (Check Email → Open) or from webmail ( https://webmail.yourdomain.com).

Email Deliverability (SPF, DKIM, DMARC)

In cPanel, go to Email Deliverability.
Here you will see recommendations for SPF, DKIM, and DMARC.
Copy the suggested DNS records and add them in Guzel.net DirectAdmin DNS panel.
Once correctly added, cPanel will show a green “Valid” status.

Required DNS Records

Host / Name	Type	Value / Example	Purpose
`@` (yourdomain.com)	A	`203.0.113.10` (FastComet IP)	Points the root domain to FastComet server
`www`	CNAME	`yourdomain.com`	Redirects www → root domain
`mail`	A	`203.0.113.10` (FastComet IP)	Mail server hostname
`webmail`	A	`203.0.113.10` (FastComet IP)	Webmail access (https://webmail.yourdomain.com)
`@`	MX	`mail.yourdomain.com` (priority 10)	Mail routing record
`@`	TXT	`v=spf1 a mx ip4:203.0.113.10 ~all`	SPF record for sender validation
`default._domainkey`	TXT	`v=DKIM1; k=rsa; p=MIGfMA0GCSq...`	DKIM record from FastComet cPanel
`_dmarc`	TXT	`v=DMARC1; p=none; rua=mailto:postmaster@yourdomain.com`	DMARC policy

Why A and MX Records Are Both Needed

A Record (mail.yourdomain.com → IP):
Tells the internet what IP address your mail server lives on.
MX Record (points to mail.yourdomain.com):
Tells other mail servers where to deliver emails for your domain.

⚠️ Without an A record, the MX record has no IP to resolve to. That’s why both must exist.

Webmail Access

There are two ways to access your mailbox:

Direct cPanel Webmail URL:
https://yourdomain.com:2096 or
https://server123.fcomet.com:2096
Custom Webmail Subdomain (recommended):
https://webmail.yourdomain.com
- Requires the webmail A record pointing to FastComet IP + SSL certificate enabled in cPanel.
- Run AutoSSL for webmail on SSL/TLS Status page in cPanel.

Mail Clients (IMAP/POP3/SMTP)

When setting up mail in Outlook, Thunderbird, or a mobile device:

Incoming Server (IMAP): mail.yourdomain.com
- Port 993 (IMAPS, SSL)
Incoming Server (POP3): mail.yourdomain.com
- Port 995 (POP3S, SSL)
Outgoing Server (SMTP): mail.yourdomain.com
- Port 465 (SMTPS, SSL) or 587 (STARTTLS)
Username: Full email address (e.g., info@yourdomain.com)
Password: The one you set in FastComet cPanel

Why SPF, DKIM, DMARC Are Needed

SPF: Authorizes FastComet servers to send mail for your domain (reduces spoofing).
DKIM: Adds a cryptographic signature so recipients can verify authenticity.
DMARC: Defines policy for handling failed SPF/DKIM checks (e.g., monitor, quarantine, or reject).

Without these, your emails may land in spam or be rejected by services like Gmail/Outlook.

Notes

DNS propagation can take 1–24 hours after changes.
Always verify records with dnschecker.org.
SSL must be enabled for mail.yourdomain.com and webmail.yourdomain.com in cPanel → AutoSSL.
FTP access is unrelated to mail. It is only used to upload website files into public_html on FastComet.

Troubleshooting

If mail isn’t delivering → check MX and SPF records.
If webmail doesn’t load → verify the webmail A record and SSL certificate.
If Outlook/phone mail doesn’t connect → make sure you’re using the correct ports and mail.yourdomain.com as the server.

✅ With this setup, your mailboxes like info@yourdomain.com or contact@yourdomain.com will be fully functional with FastComet hosting and DNS managed on Guzel.net DirectAdmin.
