Hello, I am using ispconfig 3.1 in ubuntu 18.04. I have some problem with mail, i send mail from my domain to gmail, yahoo etc. that's working fine, but when i am send mail from my domain to my other domain then i receive mail in spam.
by the way, can you test your mail server with this tools to be sure there is all settings are correct? mail-tester dot com open the site, you will get temporary email address, need to send email and then they will check your scores.
It is looks okay. Take a look into the mail header received to spam folder like Till said before If you use thunderbird mail client see screenshot how to see headers
