I keep getting this error. I used the how-to virtual-users-and-domains-with-postfix-ubuntu-7.10.
Apr 13 22:43:39 server2 postfix/smtp: 77DCB7C119: to=<firstname.lastname@example.org>, relay=hrndva-smtpin02.mail.rr.com[22.214.171.124]:25, delay=2193, delays=2193/0.01/0.43/0, dsn=4.0.0, status=deferred (host hrndva-smtpin02.mail.rr.com[126.96.36.199] refused to talk to me: 550-hrndva-mxlb.mail.rr.com 550 ERROR: Mail Refused - res.rr.com - See http://security.rr.com/rrDynamic.htm)
