5.7.1 is a Relaying Denied error. Check the Relay tabs within your LSMTP configs, or whatever you're using for your Mailer. Make sure all the IPs for the system are listed since it's Multi-homed. -----Original Message----- From: Randy Klumph [mailto:[log in to unmask]] Sent: Monday, August 16, 2004 1:49 PM To: [log in to unmask] Subject: log error message - dynamic IP The following error has been showing up in my LSMTP log. 23:40:10 mail.OPTUSNET.COM.AU( 12) <<< RCPT TO:<[log in to unmask]> 23:40:10 mail.OPTUSNET.COM.AU( 12) >>> 554 5.7.1 Rejected 140.211.116.119 is a dynamic IP 1st - LISTSERV is not configured to use the IP address indicated 2nd - it is not a dynamic IP, but we do have multiple IPs on a single box (including this one).
