Doh, I don't use a patch at all. I use debian packages from http://

Perhaps i could modify the source with that patch. Seems I need to patch either way.

I've been trying to enable SMTP auth using vchkpw with qmail today. The login works fine, but after i issue the "rcpt to" command over telnet, I get the "421 unable to read controls (#4.3.0)" error. Google told me it' s a permissions problem, but the permissions on the /var/qmail/control directory (it's actually a symlink to /etc/qmail) are:
When I telnet it looks like this:
Connected to domain.tld.
Escape character is '^]'.
220 domain.tld ESMTP
helo domain.tld
250 domain.tld
auth login

235 ok, [EMAIL PROTECTED], go ahead (#2.0.0)
mail from:<[EMAIL PROTECTED]>
250 ok
421 unable to read controls (#4.3.0)
Connection closed by foreign host.

If my memory serves me correctly, one of the older auth patches incorrectly closes the FD 3 socket.

Which patch are you trying to use ?

FYI - Bill Shupp's complete patch is the easiest to use IMHO, you can get it at
