I currently have one server install with A mail.domain.com handled by IP mx domain.com is handled by panel.domain.com I want to change it to mail.domain.com that way if someones set ups a mail on gmail to add it on the hostname instead of panel.domain.com Do i need to add to the host ipaddress mail.domain.com so it can register is as that or im stuck with the panel.domain
I'm not sure I understand what you are asking. And it seems you have several questions today in different threads, but I am too lazy to read the other threads to maybe get a clue. But you can name your e-mail server anything you want, and mailname can be different from the hostname it otherwise uses. You can also change the MX record, if that is what you are asking. The FQDN you have in MX record must have A record in name service. Maybe it would be easier to use ISPConfig to set up and maintain your servers?
Sure. If you want you can separate all main services in a server to operate own their own domain like mail.domain.com for your mail service, panel.domain.com for your web panel etc; so long they are properly setup and work; and you can always have each of them secured using LE SSL too. In relation to your mail service problem, I don't think the problem was the hostname panel.domain.com but something else which you need to check and verify. I can't help much on mail service though as I use gSuite instead.
Taleman thank you, The other questions are about the extra nginx server different than this one Ill give that a try So instead of adding Mx domain.com by panel.domain.com change that to Mx domain by mail.domain.com Do i need to add mail.domain.com on the host file Ahrasis https://www.howtoforge.com/community/threads/change-emails-hostname.13640/ I think this might have the answer. I still want to have panel.domain.com to login but for the email to have mail.domain.com but without multi server just on a single install
Ok so could not figure it out So im adding the additional mail server After i add the mail server What will happen to my emails with the panel.domain.com. Reason im asking its because i have to change mx domain.com by panel.domain.com To domain.com by mail.domain.com Wouldnt that make them stop working. Or does the a record take care of that. Do i just change the server for the client for mail and tools sync. Let me know before i add it dont want to mess it up
The MX record has to point to the server that receives the emails for a specific domain name, it is not a record that defines which server is sending email. You should add all servers that are allowed to send emails into the SPF record of that domain though.
Gotcha i understand what i do on ispconfig now, for the a record not defining the sending server i understand that my question for that was more of the mx so do i just add an extra mx record domain.com handle by newslave.domain.com and leave the other one as well domain.com handled by panel.domain.com This is the dns, but dont know if i should add it dont want to mess up what i got OLD domain.com. 1800 IN NS ns1.digitalocean.com. domain.com. 1800 IN NS ns2.digitalocean.com. ns20.domain.com. 1800 IN A ip1 ns21.domain.com. 1800 IN A ip1 domain.com. 1800 IN A ip1 *.domain.com. 1800 IN A ip1 service.domain.com. 1800 IN A ip1 nweb.domain.com. 1800 IN A ip2 mail.domain.com. 1800 IN A ip1 domain.com. 3600 IN MX 10 service.domain.com. domain.com. 3600 IN TXT v=spf1 a mx ip4:ip1 -all default._domainkey.domain.com. 3600 IN TXT v=DKIM1; t=s; et... NEW, for additional mail server - mail.domain.com domain.com. 1800 IN NS ns1.digitalocean.com. domain.com. 1800 IN NS ns2.digitalocean.com. ns20.domain.com. 1800 IN A ip1 ns21.domain.com. 1800 IN A ip1 domain.com. 1800 IN A ip1 *.domain.com. 1800 IN A ip1 service.domain.com. 1800 IN A ip1 nweb.domain.com. 1800 IN A ip2 mail.domain.com. 1800 IN A ip3 domain.com. 3600 IN MX 10 service.domain.com. domain.com. 3600 IN TXT v=spf1 a mx ip4:ip1 -all default._domainkey.domain.com. 3600 IN TXT v=DKIM1; t=s; et... domain.com. 3600 IN MX 10 mail.domain.com.
