Other SMTP Server
Connect to any SMTP server with custom configuration.
Overview
The "Other SMTP" option in Authority Mailer SMTP allows you to connect to any SMTP server - your web host's mail server, a self-hosted mail server, or any SMTP-compatible service not in our pre-configured list.
This option requires manual configuration of host, port, and authentication settings, but gives you complete flexibility.

Step-by-Step Setup Guide
Gather Your SMTP Details
Contact your email provider or check their documentation for:
- SMTP Host (e.g., smtp.yourhost.com)
- SMTP Port (587, 465, or 25)
- Security type (TLS, SSL, or None)
- Authentication (usually required)
- Username (often your email address)
- Password
Common hosting SMTP settings:
- cPanel: mail.yourdomain.com, port 465 (SSL) or 587 (TLS)
- Plesk: mail.yourdomain.com, port 465 or 587
- GoDaddy: smtpout.secureserver.net, port 465
Configure Authority Mailer SMTP
1. In WordPress, go to Authority Mailer SMTP → Settings
2. Select "Other SMTP" from the provider dropdown
3. Enter your SMTP Host
4. Enter your SMTP Port
5. Select your Encryption type (TLS/SSL/None)
6. Enable Authentication if required
7. Enter your Username and Password
8. Set your "From Email" and "From Name"
9. Save settings
Test Your Configuration
1. Click "Send Test Email"
2. Enter your email address
3. Check your inbox
If the test fails, check:
- Firewall isn't blocking the port
- Credentials are correct
- Host and port match your provider's requirements
💡 Pro Tips
- Always use TLS or SSL when available
- Port 587 with TLS is the modern standard
- Avoid port 25 - it's often blocked and not encrypted
- Test with your hosting's SMTP before buying external services
- Keep SMTP credentials secure - never share them
🔧 Troubleshooting
❓ Connection timed out
✅ The port might be blocked by your host's firewall. Contact your host or try a different port (587, 465, 25).
❓ Authentication failed
✅ Double-check your username and password. Some hosts require your full email as username.
❓ Certificate errors
✅ Try switching between SSL and TLS. Some servers use self-signed certificates that cause issues.
❓ Relay access denied
✅ Your SMTP server may restrict which addresses can send. Contact your provider.
