Hello. I have been using this setup for some years. I have done many machines this same way and never really had a problem that I couldn't fix. Well for some reason none of the emails from the users created from ispconfig (web1_.... etc) are working. All of the system users can receive and send mail but none of the web users and I don't see any erros in the mail log.
systems users as in ... (root).. first user I created (asus). web users and emails created from ISPconfig ... (web1_asus) any websites i create the email for the users wont work .. when I send a test email i see it but no errors. and the email isn't in the users mailbox
