@huzefa22 said in Same subdomain name internal and external i have an issue with the DNS, specifically emails: @Dashrender when i ping mail.abc.xyz.com i don't get a reply, the SOA is the primary and the secondary domain on the local domain. i don't know if this is what you were asking. Regards, Huzefa Never test DNS with ping. Test with nslookup. Whether you can ping or not is a factor of many things, DNS just one of them and only sometimes. nslookup tests DNS and nothing else.
