@scottalanmiller yes i shud be able to send zimbra to zimbra , i dont need to send external domain(gmail, yahoo, etc) if this works then good,
but i followed your procedure only for some reason it did not work... maybe i might be doing work in DNS settings let me start from scratch..

if i could have hired i would not have messaged here Bro... Wow never thought people here very professional
