I have a very strange problem I can't figure out. I use smail in our shop. We are in need to send and receive e-mails with our client. This particular client has changed their DNS machine not long ago. Ever since, we couldn't send or receive e-mails with each other. Trouble is, we had not experienced such problems prior to change. It seems their DNS change is OK as well. I can nslookup them, ping them, whois them as well. However, upon investigation of log file, I found this: 11/27/2001 11:18:34: [7452] remote connection from (unknown)[216.174.133.2] 11/27/2001 11:18:35: [7452] remote HELO: warning: questionable operand: 'mail.communitynet.ca': from mail.communitynet.ca source [216.174.133.2]: Remote address PTR lookup failed (Unknown host). 11/27/2001 11:18:35: [7452] remote MAIL FROM: 'LJarocki@scn.ca' target 'scn.ca' is not a valid domain; by mail.communitynet.ca [216.174.133.2]. 11/27/2001 11:18:35: [7452] remote got QUIT from mail.communitynet.ca [216.174.133.2]. 11/27/2001 11:21:31: [7502] remote connection from (unknown)[192.168.75.40] I looked at the configuration files of my mail server but I couldn't find anything to do with this particular problems as well. They tell me they have no problems with send/receive with other contacts, but with us only. I am beginning to think it may something to do with my ISP. Any ideas? I appreciate any input by now.
