I have installed a mail server under iredmail/redcube and CentOS 5.6 with ip_local: 192.168.5.x (it's a example), so I've done redirection by NAT in my router with the follow ports:
25-80-110-143-443-995-587.
In my DNS configuration from my own domain have this values:
domain: xxxx.es
MY_PUBLIC_IP_SERVER / 24 PTR xxxx.es
xxxx.es NS ns.xxxx.es
xxxx.es MX(10) iredmail.xxxx.es
xxxx.es TXT v=spf1 +a +mx -all
ftp.xxxx.es CNAME xxxx.es
iredmail.xxxx.es A MY_PUBLIC_IP_SERVER
www.xxxx.es CNAME xxxx.es
After that, I can access from outside (other network) with:
iredmail.xxxx.es/mail
I can send and receive some emails from gmail or live.com but when i try to send to other domain or receive, never happens, and i don't receive any error mail.
Could you help me showing your configuration DNS regs in a similar scenary? or what could be my problem?
Thankx for your time
