e-mail client configuration for smtp, Isp - postfix multiple domains

Hi @Taleman Ok, thanks, I didn't realize that it was also necessary to configure DNS zones in ispConfig itself.

In my mind, as I kept the dns management at my hoster, everything was configured at Ovh and I just had to point the services to the ispConfig machine.
But I understand that ispConfig also needs to route requests.

 

It is not necessary, if zones are at your hoster. Or somewhere else.

 

Ok, I understand, I'm reading the Taleman Howto " https://www.howtoforge.com/how-to-install-an-email-server-with-ispconfig-on-debian-10/"

I think I'm close from the solution to sending mails ;

Code:

host 163.172.143.149
149.143.172.163.in-addr.arpa domain name pointer srv-b.democrasite.com.

Code:

host democrasite.com
democrasite.com has address 163.172.143.149
democrasite.com mail is handled by 5 srv-b.democrasite.com.
democrasite.com mail is handled by 1 srv-b.democrasite.com.
iMacdeEitan2018:~ nabpb2018$ dig srv-b.democrasite.com |grep "ANSWER SECTION" --after-context=3
;; ANSWER SECTION:
srv-b.democrasite.com.    3600    IN    A    163.172.143.149

Code:

root@srv-b:~# hostname -f
srv-b.democrasite.com

and at my hoster, my VPS shows this :

Code:

IP address:        Reverse:
163.172.143.149    srv-b.democrasite.com.

 

WhaaaaooooooOO I get 10/10 : https://www.mail-tester.com/test-gu4kxboi0
when sending from Rouncube on server, so I think I have another problem with my Thunderbird, he says :

Code:

Error sending the message :

Sending the message failed.
The certificate is not secure because it is self-signed.
The configuration related to srv-b.democrasite.com needs to be fixed.

Not configured SSL certs for smtp I guess ;-)

 

Mmmm… You mean, I need a AAAA entry in my dns zone ?

 

You indicate at this step :

Code:

Go to ISPConfig Panel System tab, Interface Main Config and Mail tab. There set

Use SSL/TLS encrypted connection for SMTP
to SSL.

to activate the ssl for sending smtp. For SmtpUser and Smtp psswd, do I put what I want or does it have to be an e-mail account login and password already created in ispConfig?

thank you

 

Leave them empty and SMTP host: as "localhost". They are for forwarding e-mails to another e-mail server, and e-mail account and password there. I'm sure these are explained in the ISPConfig Manual.

 

Probably yes... I bought the manual, but I haven't had time to read it all yet, my apologies --°

But if I let it blank > "Please enter the admin name and admin mail address if you want to use smtp mail sending"
