I presume that the connection didn't get closed immediately. I know
that rblsmtpd closes the connection after 60 seconds. If you issue
SMTP commands, they will all result in error messages (if you need
a quick SMTP reference, see http://cr.yp.to/smtp.html).

If the environment variable RBLSMTPD is set to something besides an empty string, it should give an error code, either 4xx or 5xx depending on command line options, and whether or not the var starts with a hyphen. It's not doing that. I quote from the rblsmtpd man page: "If $RBLSMTPD is set and is empty, rblsmtpd does not block mail. "Normally, if $RBLSMTPD is set, rblsmtpd uses a 451 error code in its limited SMTP conversation. This tells legitimate clients to try again later. It gives innocent relay operators a chance to see the problem, prohibit relaying, get off the RBL, and get the mail delivered. "However, if $RBLSMTPD begins with a hyphen, rblsmtpd removes the hyphen and uses a 553 error code. This tells legitimate clients to bounce the message immediately." The last paragraph is what I'm trying to achieve. Any help there? jon

Re: using RBLSMTPD env var
try puting into your tcp.smtp.cdb file
127.0.0.2:allow,RBLSMTPD="-Go away"
then
telnet 127.0.0.2 25
Trying 127.0.0.2...
Connected to 127.0.0.2.
Escape character is '^]'.
220 rblsmtpd.local
helo test
250 rblsmtpd.local
mail from: [EMAIL PROTECTED]
250 rblsmtpd.local
rcpt to: [EMAIL PROTECTED]
553 Go away
See if that works. Just so you know you are on the right track :)

So it was just timing out the connection before it got a chance to say "553 yada yada yada." I did a copy and paste of HELO, mail from, etc and it did give the 553 error message. Thanks. I gotta go increase that 2 second timeout. What was I thinking?! jon
