Fix SMTP Email Error 450 – Causes, Solutions, and Prevention Tips | |
SMTP Email Error 450 is a temporary failure message that typically appears when an email server is unable to deliver a message due to issues like a full recipient mailbox, greylisting, or server unavailability. The error often reads: "450 Requested mail action not taken: mailbox unavailable." This does not mean the email is permanently undeliverable—most servers will attempt to resend the message later. Common causes include incorrect recipient addresses, DNS issues, or restrictions on the receiving mail server. To resolve this error, verify the recipient's email address, ensure their mailbox isn’t full, and confirm that your domain isn’t blacklisted. If the error persists, contacting your email service provider or system administrator may be necessary to check server-side configurations. Proper server maintenance, validated DNS records (SPF, DKIM, DMARC), and clean mailing lists can prevent future occurrences of SMTP 450 errors and ensure smooth email delivery.  | |
