Hi,
I want to send Mails via SMTP from another server to my iredmail server.
I'm using SMTP for that, but the iredmail server wont let user auth without a secure connection on port 25.
TLS on port 587 works just fine, but I need port 25 too (even if its unsecure)
#smtpd_tls_auth_only = yes in /etc/postfix/main.cf is already commented.
When trying to send a mail via smtp p[ort 25 I get this error:
smtp-server: 503 5.5.1 Error: authentication not enabled/var/log/mail.log:
