Why Can't I Send or Receive Emails?

If you can't send or receive emails, the issue is usually one of a handful of common problems. Here's how to diagnose and fix it.

Check Webmail First

Log in to webmail at yourdomain.com/webmail. If email works in webmail, the problem is likely with your email client or device settings - not the server itself.

Common Causes and Fixes

Can't Receive Email

• Quota is full - check your email account's storage in cPanel. If it's at 100%, incoming mail will be rejected. Delete old emails or increase the quota.
• Wrong MX records - verify your domain's MX records are correctly pointing to dotCanada's mail servers in cPanel > Zone Editor.
• Email is in spam - check your spam or junk folder in webmail or your email client.

Can't Send Email

• Wrong SMTP settings - verify your outgoing server is mail.yourdomain.com, port 465 (SSL) or 587 (STARTTLS), with authentication enabled.
• Wrong password - try logging into webmail with the same credentials to confirm your password is correct.
• Hourly sending limit reached - cPanel enforces a per-hour limit on outgoing email. Wait an hour and try again.
• ISP blocking port 25 - some internet providers block port 25. Use port 587 or 465 instead.

If none of these fix the issue, contact our support team and let us know what error message you're seeing.
