RFC 5248, "A Registry for SMTP Enhanced Mail System Status Codes", June 2008

Errata ID: 8207
Status: Reported
Type: Technical
Publication Format(s) : TEXT
Reported By: S. Moonesamy
Date Reported: 2024-12-07

Section 2.4 says:

| X.5.3  | 451           |

It should say:

| X.5.3  | 452           |

Notes:

Section 4.5.3.1.10 of RFC 5321 states the following:

"If an SMTP server has an implementation limit on the number of RCPT commands and this limit is exhausted, it MUST use a response code of 452 (but the client SHOULD also be prepared for a 552, as noted above)."

The "451" Associated Basic Status Code in the Enhanced Status Codes Registry entry for X.5.3 should be "452" given what is stated in RFC 5321.
