SMTP Error Codes

Hi,

1. Is there an official link/article/documentation for SMTP error codes?
2. I expect/want to be able to find all kind of SMTP error codes from one single place.

I even googled and finding partial information here and there.

Hope community experts have the answer.

Hi ong-hh,

Although I can find SMTP status/error/reply codes (from AnswersThatWork.com), there is no official standard drafted out for SMTP error codes?

In fact, I've already downloaded one.

check:

http://www.greenend.org.uk/rjk/2000/05/21/smtp-replies.html

There are all codes ordered numerically in text mode and grouped by command

Hi Mikkk,

http://www.greenend.org.uk/rjk/2000/05/21/smtp-replies.html

But I don't find a particular error code which I'm currently facing with our SMTP server: 571 5.7.1 Message Rejected

from http://cr.yp.to/smtp/request.html :
Standard SMTP uses RFC 821, however, clients cannot take this list seriously. For example, some servers use code 571, in violation of RFC 821. (Apparently some people are under the delusion that RFC 1893 extended the list of SMTP codes. RFC 1893 clearly states that its codes---which aren't 3-digit numbers---are for use in a different context, namely DSNs.) The IETF subsequently permitted codes 252 and 555, again violating RFC 821

Definition of RFC1893: http://www.ietf.org/rfc/rfc1893.txt
