My domain name is www.example.com & my server name is server.
My users send & received mail with each other by usning IP(192.168.0.1) but when they using server.example.com, then mail not sedn & received at users sites.
This happen coz DNS could not resilve FQDN, but i cant understand how can i write this zone file.
I want that my users can send & received mailz by using both IP or FQDN.
Anyone can tell me the format of this.
Well, what exactly is your DNS setup? That is, what DNS server do you use, on what address, what's in your client computers' /etc/resolv.conf, etc.?
