Hello, what configuration did you modify? Is the posfix service running normally? Is there more information?

There where a tab with like smtp or something like that, I could enter the mailserver adress, server, port, fqdn, user and password

postfix is running normal

You can navigate from:

App Store → Mail Server → Setting → Domain list → User

Then you will see your SMTP settings for client connection.

Thank you, I checked my settings, but still can't send mail through it

Your mail server domain must be encrypted with SSL certificate. does SSL Certificate has been enabled yet?

All is done, sending a mail from aaPanel ain't a problem, but I can't connect from a Client outside.

aaPanel_Kern

Hello, what information does the client prompt? What port is used?

aaP_uwe.sarpe

@"aaPanel_Kern"#p* authentification failed, password and username filled by copy and paste, Port 587
#BEGIN_POSTFIX_RELAY
relayhost = [mail.sarpetronic.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = static:smtp@domain.tld:pw
smtp_sasl_security_options = noanonymous
#END_POSTFIX_RELAY

Update: I tryed Port 25 with no encrypition, the mailserver accept that data and mails goes into sent folder, but aren't sended

App Store → Mail Server → Setting → Domain list → User

The SMTP service settings for client connection are open. but it is the issue of SSL Certificate that validate with domain name in mail server.

You may try connect with client app with the domain name (domain.tld) as outgoing/ongoing servername, do not use prefix mail.domain.tld.

Hello, you can check the logs of the mail server to see why it cannot be sent.

Actually that can't be the case, in the certificate for the website I have SAN domain and mail plus www is alternative, in the setting for the mail server it is clearly only mail.sarpetronic.com
If I change the smtp server to onlysarpetronic.com, I get a cerificate warning
