dovecot dict protocol

Hi there

is there any written specification for dovecot dict protocol instead of the code?

Small example is in docs on https://wiki.dovecot.org/AuthDatabase/Dict and theere is link for all commands/reply in the code https://wiki.dovecot.org/AuthDatabase/Dict

I’m writing small dict server and need some explanation for

CMD: I, what does the flags means and how should the result looks like CMD: D, I thing this is the same as C, but coud be done later /async/

The reply codes are not very clear. I understand O, N, F. The rest is strange to me.

Maybe this is good question do devel mailing list.

regards
	Peter
