I don't remember exactly, I studied a lot of documents and found same tables that lead me to that decision (to have a close correspondence to 5.x.x formats).
These are all definitions within chkuser_settings.h
#define CHKUSER_NORCPT_STRING "511 sorry, no mailbox here by that name (#5.1.1 - chkuser)\r\n"
#define CHKUSER_RESOURCE_STRING "430 system temporary unavailable, try again later (#4.3.0 - chkuser)\r\n"
#define CHKUSER_MBXFULL_STRING "522 sorry, recipient mailbox is full (#5.2.2 - chkuser)\r\n"
#define CHKUSER_MAXRCPT_STRING "571 sorry, reached maximum number of recipients for one session (#5.7.1 - chkuser)\r\n"
#define CHKUSER_MAXWRONGRCPT_STRING "571 sorry, you are violating our security policies (#5.1.1 - chkuser)\r\n"
#define CHKUSER_DOMAINMISSING_STRING "511 sorry, you must specify a domain (#5.1.1 - chkuser)\r\n"
#define CHKUSER_RCPTFORMAT_STRING "511 sorry, recipient address has invalid format (#5.1.1 - chkuser)\r\n"
#define CHKUSER_RCPTMX_STRING "511 sorry, can't find a valid MX for rcpt domain (#5.1.1 - chkuser)\r\n"
#define CHKUSER_SENDERFORMAT_STRING "571 sorry, sender address has invalid format (#5.7.1 - chkuser)\r\n"
#define CHKUSER_SENDERMX_STRING "511 sorry, can't find a valid MX for sender domain (#5.1.1 - chkuser)\r\n"
#define CHKUSER_INTRUSIONTHRESHOLD_STRING "571 sorry, you are violating our security policies (#5.7.1 - chkuser)\r\n"
#define CHKUSER_NORELAY_STRING "553 sorry, that domain isn't in my list of allowed rcpthosts (#5.5.3 - chkuser)\r\n"
I may change default definitions if there is any problem (but anyone may change as he/she likes).

Can somebody tell me why chkuser (I'm using 2.0.8) gives a 511 response to a "user not found" error?
RFC 821 gives 550 as the correct response -- Cheers Alastair Battrick www.battrick.org
