Fixing Business Email Delivery Problems

Email issues fall into two categories: not sending (outbound) and not receiving (inbound). Here is how to diagnose each.

Not Receiving Emails

Check 1 — Verify MX Records
  1. Go to mxtoolbox.com/MXLookup.aspx
  2. Enter your domain
  3. Confirm MX records point to mail.yourdomain.co.ke or Braysons Host mail servers

If MX records are wrong, update them in cPanel → Zone Editor.

Check 2 — Check Spam/Junk Folder

Emails may be delivered but filtered to spam. Check your webmail spam folder at https://yourdomain.co.ke/webmail.

Check 3 — Mailbox Quota

A full mailbox rejects incoming mail.

  1. Log into cPanel → Email Accounts
  2. Check the storage usage next to your email address
  3. If full, delete old emails or increase the quota

Not Sending Emails

Check 1 — SMTP Settings

Verify your email client is configured with:

SMTP Server: mail.yourdomain.co.ke

SMTP Port: 587 (STARTTLS) or 465 (SSL)

Authentication: Required

Username: your full email address

Password: your email password

Check 2 — Check if Your IP is Blacklisted

Visit mxtoolbox.com/blacklists.aspx and enter your server IP. If blacklisted, contact our support team — we will request delisting.

Check 3 — SPF Record

Ensure your domain has a valid SPF record:

v=spf1 include:braysons.co.ke ~all

Add this as a TXT record in cPanel → Zone Editor.

Testing Email Delivery

Send a test email to mail-tester.com — it will score your email configuration and highlight any issues.
