I have now tried this on a working system using MySQL, to make sure the courier install is otherwise correct, and only made the most minimal changes from using courier-authlib-mysql to using courier-authlib-pipe. I copied the authProg from the previous server and only changed the DB lookup line to point to the local MySQL server (instead of sqlite) and tested the script itself to make sure it works without error.

However it's still failing to write stdout to authdaemond.

Perhaps I completely misunderstand how authlib-pipe is meant to work. The perl example indicates the authProg script should just read stdin input, do an auth test, and return the results to stdout output in a certain format. Can someone confirm that that is indeed how authlib-pipe is supposed to work ?

This is a set -x trace from the mail logfile for an IMAP connection and it seems to indicate all is well until it goes to output to STDOUT which obviously fails.

Can anyone suggest why a simple write to STDOUT would fail ?
