I installed postfix as a mail server on my Ubuntu server but when I try to send a mail from rainloop I get an error in the logs saying access is denied.My domain name is dimdams.comThe subdomain for rainloop is webmail.dimdams.comThe one for postfix is mail.dimdams.comI also made an MX record on cloudflare but I don't really know about it so I don't know if that could be the cause.I looked on other forums how to correct this error but each time it says to add a hostname except that I don't know which one
Here is my main.cf configuration :
