Sorry for the previous message, this is indented better.

Good morning,

I recently installed chkuser in response to a SpamCop listing. I have a user getting addresses rejected that we know exist. The addresses are in valias and work fine when I send a message. The user in question is recently getting rejections. Here is a sample of the qmail-smtp log.

2005-03-15 17:06:06.731444500 CHKUSER rejected rcpt: from <[EMAIL PROTECTED]::> remote <> rcpt <[EMAIL PROTECTED]> : not existing recipient

2005-03-16 08:37:28.526532500 CHKUSER accepted rcpt: from <[EMAIL PROTECTED]::> remote <[]> rcpt <[EMAIL PROTECTED]> : found existing recipient

You should enable CHKUSER_RCPT_FORMAT and see if there are any strange characters (invisible in log) that make the address unusable (you have rcpt not existing when you could have INVALID FORMAT)

You could also modify chkuser.c this way, in order to track better the rejected recipient... The following change display complete address length, so you may check if the address length corresponds to what you read:

static void chkuser_commonlog (char *sender, char *rcpt, char *title, char *description) {

char str[30];
sprintf (str, "%d", strlen (rcpt));

  substdio_puts (subfderr, "CHKUSER ");
  substdio_puts (subfderr, title);
  substdio_puts (subfderr, ": from <");
  substdio_puts (subfderr, sender);
  substdio_puts (subfderr, ":" );
  if (remoteinfo) {
        substdio_puts (subfderr, remoteinfo);
  substdio_puts (subfderr, ":" );
  if (identify_remote) substdio_puts (subfderr, identify_remote);
  substdio_puts (subfderr, "> remote <");
  if (fakehelo) substdio_puts (subfderr, fakehelo);
  substdio_puts (subfderr, ":" );
  if (remotehost) substdio_puts (subfderr, remotehost);
  substdio_puts (subfderr, ":" );
  if (remoteip) substdio_puts (subfderr, remoteip);
  substdio_puts (subfderr, "> rcpt <");
  substdio_puts (subfderr, rcpt);
  substdio_puts (subfderr, ":" );
  substdio_puts (subfderr, str);
  substdio_puts (subfderr, "> : ");
  substdio_puts (subfderr, description);
  substdio_puts (subfderr, "\n");
  substdio_flush (subfderr);

I'm not sure just why this is happening, I do not have CHKUSER_RCPT_FORMAT defined, in fact the only changes I made to the chkuser_settings.h was to uncomment CHKUSER_ALWAYS_ON and set the CHKUSER_MBXQUOTA to "90" in my qmail-smtpd run script.

I had the user send me the message in question and I noticed that the addresses had single qoutes in them,


I would suspect that was the issue except that this address book worked prior to installing chkuser, and the qmail-smtpd log shows the address correctly when it is rejected.

chkuser uses and logs exactly what receives from qmail-smtpd.



Any ideas?
