Also my server send to gmail to inbox but on yahoo not receive anything

I need a recomandation for yahoo to work good

My test email without smtp relay on is like this : https://www.mail-tester.com/test-7l3jetzt0

I need to use port 25 by default for SMTP RELAY or SMTP, where I can change to have 25 the port for my internal email servers and to use 587 for the secured external email traffic?

I chmod 644 that file related to DKIM but no warning was disable, any tips? https://imgur.com/a/hyjTsyP

aaPanel_Kern Hey Kern, My config file is the default one, i put config file here, now I have the smtp relay off because i try to put the ssl of main domain to the webmail domain and not get forced by SSL, here it goes the config file, take a look, default one: # See /usr/share/postfix/main.cf.dist for a commented, more complete version

Debian specific: Specifying a file name will cause the first

line of that file to be used as the name. The Debian default

is /etc/mailname.

#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

appending .domain is the MUA's job.

append_dot_mydomain = no

Uncomment the next line to generate "delayed mail" warnings

#delay_warning_time = 4h

readme_directory = no

See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on

fresh installs.

compatibility_level = 2

Ok, I have put the SSL from main domain to the mail section domain how is it in tutorial, because i was forget to put that in the start, now I just only need to check if the smtp relay work, and if it will send to inbox in yahoo mail.

Do you think is better for me to use cloudflare than contabo dns manager? Because my emails are not going at all in yahoo mail but in google it works like a charm

I tested Outlook on my roundcube = OK, works
I tested Yahoo on my roundcube = Not work at all host mta5.am0.yahoodns.net[67.195.228.111] said: 553
5.7.2 [TSS09] All messages from 62.169.30.22 will be permanently deferred;
I tested Google on my roundcube = Works on Inbox

All tests was taken with sending and receiving emails from aapanel mail.

Hi Kern, I was managed to make it WORK, I installed fluent SMTP (free plugin) to wordpress, I have put aapanel details for user login into fluent SMTP, and the test mail was going to the GMAIL inbox, now I try to make all the settings for my email to go good in Yahoo-Mail, because my mails are not send at all, if you have some tips regarding this Yahoo mail issue will be good, if not I will try to fix myself from internet resources.

Best, HAIL AAPANEL!

Kern I give you a idea for aaPanel and your team, you could give the mobile android app for free for all users and you can integrate a section or a popup for sale of the premium service & support for your aaPanel, this could boost mobile traffic and sales big time, just think about, both sides win, we can restart from phone the server or see parameters an you could catch bigger market.

C ya soon, that's all on this, I managed to make it work everything.
