Cannot send, but can receive
- Check SMTP settings: port 465 (SSL) or 587 (STARTTLS) with authentication ON
- Some ISPs block port 25 — never use it for client sending
- Verify the password (username is the full email address)
Cannot receive mail
- Mailbox full? Delete large old mail or increase the quota from your client area
- Check the domain has not expired and MX records are intact (Domains → DNS)
- Ask the sender for the bounce message — it usually states the exact reason
My emails go to recipients' spam
- Confirm SPF and DKIM records are published for your domain
- Avoid spammy subject lines, all-caps, and large image-only mails
- Do not send bulk marketing from your business mailbox — use a proper campaign tool
Password not working
Reset the mailbox password from your client area (Services → your email service). After changing it, update the password on all devices to avoid lockouts from repeated failed logins.
