How work name resolution in Postfix?
I have an internal server that resend mail to another box (in the same IntraNet). If I put in my local /etc/hosts something like: 192.168.1.25 mail.aaa.tld the box do what I want: # ping mail.aaa.tld PING mail.aaa.tld (192.168.1.25) 56(84) bytes of data. 64 bytes from mail.aaa.tld (192.168.1.25): icmp_seq=1 ttl=64 time=0.181 ms 64 bytes from mail.aaa.tld (192.168.1.25): icmp_seq=2 ttl=64 time=0.181 ms 64 bytes from mail.aaa.tld (192.168.1.25): icmp_seq=3 ttl=64 time=0.184 ms . . . # telnet mail.aaa.tld 25 Trying 192.168.1.25... Connected to mail.aaa.tld. Escape character is '^]'. 220 mail.aaa.tld ESMTP . . . . but Postfix seems to still search the real IP via DNS. Why? Any trick/config/workaround to force Postfix to consider /etc/hosts? Thanks, B.
