if you don't have /etc/tcp.smtp.cdb or if you dont have things like in an uncompiled /etc/tcp.smtp:
127.:allow,RELAYCLIENT="" :deny if you are using plain tcpserver you should have -x /etc/tcp.smtp.cdb on your command line, it specifies who is allowed to relay via your smtp server. the purpose of the /var/qmail/control/rcpthosts file specifies what domains you will accept mail for, if the domain is not on this list, it will bounce back the message. well to simply test open relay, try doing the telnet xxx.xxx.xxx.xxx 25 mail from, rcpt to dance, if you can send emails even if your ip is not allowed as a relay client in the /etc/tcp.smtp.cdb then you are open relay, but i doubt if you could send an email using the smtp server even if your ip range is not allowed. i hope that cleared some things. ----- Original Message ----- From: "Mike Liguit" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Thursday, June 26, 2003 4:12 PM Subject: Re: [plug] open relay ? > If you don't have the file /var/qmail/control/rcpthosts, then your > server is an open relay. > > Anyway, I believe qmail has good documentation on selective relaying and > open relaying.
