I've installed bind on centos 4.3.. This is a part of my config file: example.com. IN MX 10 mail.example.com. example.com. IN MX 15 mail1.example.com. example.com. IN MX 20 mail2.example.com. mail.example.com. IN A IP mail.example.com. IN A IP
I've installed bind on centos 4.3.. This is a part of my config file: example.com. IN MX 10 mail.example.com. example.com. IN MX 15 mail1.example.com. example.com. IN MX 20 mail2.example.com. mail.example.com. IN A x.x.x.x mail1.example.com. IN A x.x.x.x mail2.example.com. IN A x.x.x.x Every seems to be fine, but I'm constantly receiving messages in my 3 MX servers, even if mail.example.com (the less MX record) is available waiting for connections from outside... Why if my less mx record server is available the others servers are constantly receiving messages for my domain? Thanks for your time Israel
More details: 1. The 3 servers are in diferents networks... 2. My higher's mx servers (mx 15 and mx 20) receive a lot of legitimate mail.. It also received a lot of spam too.... :-( 3. MX1 server is in the main network (backbone).. It's the most accesible network of the others Mx's 4. Mx 2 and Mx 3 are constantly receiving messages... Like if the dns were the same MX record for the three servers..

even more details: 1. I use Mailscanner/postfix in the 3 MX's servers. 2. Using dig I get exactly the same of what I have in my bind server. 3. http://dnsreport.com/ reports no problem at all. 4. I'm not using any greylisting.... Yet.. I'm setting right now spamassassin with mailscanner..
