Business email on your own domain: full setup

Business email on your own domain in 30 minutes

To run corporate email like you@company.com you need four steps: add the domain, publish MX, SPF, DKIM and DMARC in DNS, create mailboxes, and open webmail. MX routes incoming mail to the server, while SPF/DKIM/DMARC authenticate your outgoing mail and stop spoofing. Let's walk through every record with real values.

Step 1. Add the domain

In the panel open "Domains" → "Add" and enter company.com. The system immediately creates the service mailboxes noreply@ and support@ and shows ready-made DNS records with your unique DKIM key. Publish them at your DNS provider (Cloudflare, registrar, etc.).

Step 2. Publish DNS records

The minimum set to receive and send mail:

Type  Host               Value                                           TTL
MX    @                  10 mail.yourtrend.online                        3600
TXT   @                  v=spf1 ip4:5.39.41.216 ~all                     3600
TXT   mail._domainkey    v=DKIM1; k=rsa; p=MIGfMA0GCSq...IDAQAB          3600
TXT   _dmarc             v=DMARC1; p=none; rua=mailto:dmarc@company.com; fo=1  3600

• MX — where to deliver incoming mail. Priority 10, host mail.yourtrend.online.
• SPF — which servers may send as your domain. Start with ~all (softfail), tighten to -all later.
• DKIM — the cryptographic signature. Selector mail; take the exact p= from the domain card; each domain has its own key.
• DMARC — policy when SPF/DKIM fail. Start with p=none and collect rua reports, then move to quarantine and reject.

If the domain is on Cloudflare, YourTrend can publish these records in one click via an API token. The free deliverability lab helps verify publication.

Step 3. Wait for verification

DNS propagates in minutes to hours. Once the records are visible, the domain becomes verified — only a verified domain may send and use webmail. The panel's check reads content, not mere presence: is your egress IP in SPF, does MX point to mail.yourtrend.online, does the published DKIM match your key.

Step 4. Create mailboxes and aliases

In the domain card click "Mailboxes" and add the addresses you need: info@, sales@, hr@. Each exposes IMAP/POP3/SMTP settings, a sender name and a signature. Handy patterns:

• Aliases — several addresses into one mailbox (sales@ and partners@ → one box).
• Catch-all — funnel mail sent to any non-existent address on the domain into one mailbox.
• Autoresponder and filters (Sieve) — sort mail into folders and reply while away.

Step 5. Webmail and clients

YourTrend webmail lives at i.yourtrend.online: a single login gathers every mailbox across all your domains with folders, search, attachments and unread counters. For desktop and mobile clients use the standard parameters:

IMAP:  mail.yourtrend.online : 993 (SSL/TLS)
POP3:  mail.yourtrend.online : 995 (SSL/TLS)
SMTP:  mail.yourtrend.online : 587 (STARTTLS) / 465 (SSL)
Login: full mailbox address, password from the panel

What to improve after launch

1. Tighten SPF to -all once every legitimate source is accounted for.
2. Raise DMARC to p=quarantine, then p=reject, watching the reports.
3. Add MTA-STS and TLS-RPT to enforce TLS on inbound mail.
4. Register with the postmaster tools of Gmail, Outlook and Yahoo to monitor reputation.

Need campaigns and transactional mail from the same domain? They run through the same engine and signature; see the features and the API documentation. And if conversation privacy matters, look at secure email for business.

Migrating from your old provider with zero downtime

Moving corporate email need not interrupt work. A nerve-saving order: first set up the domain and mailboxes on the new platform and, a day before the switch, lower the MX record TTL to 300 seconds so the change propagates fast. Recreate the same addresses your staff had and, if needed, set forwarding from the old server to the new one during the transition. Migrate the mail archive over IMAP (for example with imapsync) so old correspondence lands in the new mailboxes. On switch day, point MX to mail.yourtrend.online and add our egress IP to SPF; for a few hours mail may arrive at both servers while DNS propagates — that's normal. After verifying, raise the TTL back and gradually tighten DMARC. Don't delete the old mailboxes for at least a week so you don't lose the tail of messages sent before the switch. The deliverability lab helps confirm the new records are visible and correct.

Mailbox reliability and security

Corporate mail is a critical service, so build in basic resilience. Add a backup MX record with a higher priority number (for example 20 mail.yourtrend.online alongside the primary 10) so senders retry delivery if the first host is unreachable. Give each employee a separate mailbox with a strong, unique password, and hand out shared addresses like info@ through aliases rather than a shared login. Allow access over TLS only (ports 993/995 and 587/465), and don't delete the service mailboxes noreply@ and support@ — they're protected and needed by the platform. Back up important correspondence over IMAP regularly, and keep the active-staff list in check, disabling mailboxes on offboarding.
