The remote host is saying that that's where the mail is coming from. In general reverse lookups don't lie, and apparently the remote host is using a dynamic IP blacklist that includes either this address specifically or a range that happens to include this address. FWIW when i telnet to port 25 of 140.211.116.119, concretely I get 220 tr.wou.edu (LSMTP for Windows NT v1.1b) ESMTP server ready Note that we're really talking about LSMTP here, not LISTSERV, and unless you have LSMTP set to bind to a specific IP, it will use the first available IP on the machine. See below for instructions on how to force the binding to a single IP. >2nd - it is not a dynamic IP, but we do have multiple IPs on a single >box (including this one). Are you SURE that the IP in question is not one of the ones assigned to the box? If it is, you either need to remove it from the machine or change how it is listed in DNS. Right now it looks dynamic to me. You can bind LSMTP to one IP address, using the following instructions: 1. Open the \LSMTP\config.dat file in Notepad or another plain text editor (be sure it's a plain text editor; Microsoft Word or even Wordpad are not recommended here). 2. Add the following line at the bottom of the file: LocalIPAddress=1.2.3.4 (obviously you enter the correct IP that LSMTP should be 'listening' on) 3. Save the file. 4. Open a DOS box and CD into the LSMTP directory. Issue the following command at the DOS prompt: LSCP RELOAD CONFIG At this point LSMTP should be listening only on the IP you specified in step 2. To change the port, use the same procedure as above, but the variable to add is SmtpListenerPort=xxx where xxx is the number of the port you want LSMTP to listen on, for instance, SmtpListenerPort=10025 You can add both values to the file at the same time if you want; you don't have to do this in two separate operations.
