The whole email and DNS system is fucked up!

What have you done now? :D

@Linux nothing :O

I was adding MX records and I think I did it pretty good. But I think it's a dumb system.... Or I understand it to little...

Still... I get errors regarding the reverse DNS entry. I feel useless.

@Divisionbyzero
Why is it a good system? It works perfect and when you understand it - it is logical and simple.

The reverserecord is something you set at your hostingprovider.

@Linux I did, but when I enter the websites domain it complains about not valid hostname. When I enter the FQDN it complains about hostname not matching.

I talk about SMTP teats

@Divisionbyzero
For example:
You have a website called zero.com
You have a emailserver that is called mail.zero.com
You set up a A record to mail.zero.com with the IP to that server.
Then you add a MX record at @, like this:
@ MX 10 mail.zero.com

@Linux what is when both are on one server?

@Divisionbyzero

@ MX 10 zero.com

It is not recommended to have the website and mailserver on the same server thou.

Why is that?

@Divisionbyzero
Website is hacked - the reputation of the server goes down the drain.
Also, if they want to send spam from your domain, there is nothing that stops them because SPF will align.

@Linux OK, if that happens I will take the gun anyways. Because my wife is going to kill me with a broken bottle, if she gets me.

@Divisionbyzero
Haha, sounds like a bad relationship ;)

@Linux it's the opposite. 😅

@Divisionbyzero
Thats nice :)

reading all comments and was able to understand everything. +1 for this achievement, a year ago I'd be like: WTF are they talking about lol

thanks both of ya @linux & @Divisionbyzero

@gitpush you mean the women part, aren't you? 🤔

@Divisionbyzero oh that part I did not understand lol

@Jop- I call the whole DNS record system fucked up. Not emails persee.

@gitpush sometimes I forget that it's a developer community. 😂

@Divisionbyzero haha better not do that again :P

@Divisionbyzero
No, the DNS system is solid.
