Hello. I've read Manual and overview related topics at forum and I can't understans one minor thing which make major problem. Lets say that I have Joomla installed at Website and another Joomla at subdomain: www.joomlaproduct,com and demo.joomladroduct.com. Both are created as website. Below I mean in subdomain the address which looks like subdomain just. At domain registrant I have personal name server records like ns1.joomladroduct.com and ns2.joomladroduct.com It's obivious that DNS zone for mail website should be: Code: A demo 220.127.116.11 0 A mail 18.104.22.168 0 A joomlaproduct.com. 22.214.171.124 0 A ns1 126.96.36.199 0 A ns2 188.8.131.52 0 A www 184.108.40.206 0 CNAME ftp.joomlaproduct.com. joomlaproduct.com. 0 MX joomlaproduct.com. mail.joomlaproduct.com. 10 NS joomlaproduct.com. ns1.joomlaproduct.com. 0 NS joomlaproduct.com. ns2.joomlaproduct.com. 0 TXT joomlaproduct.com. v=spf1 +a +mx -all 0 but what should be at Subdomain DNS zone? I guessed the same, but after reading forum I'm confused with next settings as idea Code: A demo.joomlaproduct.com. 220.127.116.11 0 A ns1 18.104.22.168 0 A ns2 22.214.171.124 0 CNAME ftp.demo.joomlaproduct.com. demo.joomlaproduct.com. 0 MX demo.joomlaproduct.com. mail.demo.joomlaproduct.com. 10 NS demo.joomlaproduct.com. ns.demo.joomlaproduct.com. 0 NS ns1 ns1.demo.joomlaproduct.com. 0 NS ns2 ns2.demo.joomlaproduct.com. 0 TXT demo.joomlaproduct.com. v=spf1 +a +mx -all 0 but in fact I don't need MX, TXT records for subdomain, but CNAME ftp must be because there separate FTP user. Though it's not necessary because connection could be established by IP Of cause I mean in subdomain separate website which just looks like subdomain. Please, help me to find the truth. Thanks.
