We are receiving the following in our email logs: Mar 09 08:12:15 mail01.raystedman.org postfix/smtpd[13431]: warning: hostname mail01.raystedman.org does not resolve to address 192.168.122.12
This warning is in fact true. I believe something is not configured correctly. The postfix mail server at mail01.raystedman.org has two network interfaces: WAN and LAN. The WAN hostname is mail01.raystedman.org which resolves to 166.88.17.149. The LAN hostname is mail01-p.raystedman.org which resolves to 192.168.122.12. main.cf contains: mynetworks = 192.168.122.0/24, aaa.bbb.ccc.ddd/32, 127.0.0.0/8 where aaa.bbb.ccc.ddd/32 is the only acceptable WAN address (protected here and at the firewall level). We also accept email from the LAN and localhost networks. We recently started accepting email from the single WAN address and added the IP to mynetworks. This likely has something to do with the configuration issue. Thanks, Greg www.RayStedman.org
