Quick answer: Use your domain's SMTP server with port 587 and TLS encryption (example:
smtp.yourdomain.com).Recommended SMTP settings
- Outgoing mail server (SMTP): smtp.yourdomain.com
- Port: 587
- Encryption: TLS (STARTTLS)
- Authentication: Required — use your full email address and password
Notes and tips
- Make sure the email account you use exists in your control panel (Email Accounts) and the password is correct.
- Use your full email address as the SMTP username (e.g.,
user@yourdomain.com). - If your site is hosted on Amicatek WordPress hosting, these settings will work for most SMTP plugins (WP Mail SMTP, Post SMTP, Easy WP SMTP, etc.).
- If you prefer, you can use third-party transactional email services (SendGrid, Mailgun, Amazon SES) — they often provide higher deliverability and API or SMTP options.
DNS: SPF, DKIM and DNS records
To improve deliverability add SPF and DKIM records for your sending domain:
- SPF: Include Amicatek mail servers or your mail provider in the SPF TXT record.
- DKIM: If your mail service supports DKIM, add the provided DNS records.
Testing
Use an SMTP test tool or the plugin's test email feature to verify settings. Check spam folders and message headers to confirm SPF/DKIM alignment.
