Dear All

I have jus migrated to centos 5 and jus wondering why n where this problem could be

server A which is running for the past 2 years used as my primary dns and mail server

redhat linux 8 sendmail ver-8.12.5-7 bind ver -9.2.1-9

since the server is old and is prone to all security problems i have a new machine which i have installed the following and will replace my existing redhat dns + mail server

centOS 5 bind-9.3.3-8.el5 sendmail-8.13.8-2.el5 mailscanner latest spam assassin + clamav - latest dkim filter plus the lastest updates

now when i send a mail to my yahoo account from my old redhat server it goes fine to inbox

I disconect my old red hat server cable and plug it new centos server since both have the same IP's and when i send a mail from the centos server it goes to yahoo bulk mail and not to inbox

receving is fine with both server

i am jus wondering why. even i see the DKIM filter inserts a global key ( text record of my DNS ) in my mail logs and also in the yahoo when i see full headers in yahoo

apprecite if someone could help me

Since you mention bind, is the system serving as dns server also? Does it have the same FQDN as the old server?
