Ok, call me stupid. I forgot how our network was setup for a minute (Ok maybe longer). That fixed everything.

The .cdb file is correct; we've verified it. The problem is therefore one of the following: -you're not actually running qmail-smtpd from tcpserver -your tcpserver invocation for qmail-smtpd is not referring to this .cdb -tcpserver can't read this .cdb -your connections are actually coming from IP address you haven't set the rules for Please post the script you're starting tcpserver/qmail-smtpd with.

No. This will allow anyone to connect to your SMTP server. Whether they can send mail or not depends on the contents of rcpthosts, the envelope recipient of the message they try to send, and whether the RELAYCLIENT environment variable is set. A default rule of :deny almost _never_ makes sense for the .cdb file controlling access to your SMTP daemon.

What errors are you getting? Please show us the exact text of all error messages you receive, errors shown in the qmail logs, etc. Preferably duplicate the error by telnetting to port 25 from one of your clients which should be allowed to relay, and show us a transcript of an SMTP session failing; some MUAs helpfully hide all useful error messages. > Here is what I used to make the tcp.smtp.cdb file: > > 192.168.:allow > 192.168.:allow,RELAYCLIENT="" > :allow The first line is unnecessary; the second line covers it. Otherwise, it looks good. > After changing the tcp.smtp.cdb file I restarted both tcpserver and > qmail. How did you "change" the file? Did you change tcp.smtp, then run tcprules on it to create tcp.smtp.cdb? Please show us.

MAYBE just try creating /etc/tcp.smtp with the above data in it, then either run '/etc/rc.d/init.d/qmail cdb' (if you installed as per LWQ), or type: tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp And make it world readable by: chmod 644 /etc/tcp.smtp.cdb This SHOULD help you out somewhat.
