How to Troubleshoot and Fix Common SMTP Email Error 421 Issues
Experiencing an SMTP Email Error 421 usually indicates that the mail server is temporarily unavailable or has rejected your connection request. This error often occurs due to server overload, IP blacklisting, or exceeding email sending limits. To resolve the issue, first verify your email settings, including SMTP server details and port numbers. Check your internet connection and ensure your IP is not flagged for suspicious activity. Reducing bulk email sending and waiting before retrying may also help. If the error persists, contact your email service provider to confirm server status or request unblocking. Timely action prevents communication delays.
