Hello, I made tests with mail addresses and I found something strange : when I send a mail to a user who is not in the site's users, the mail is arriving in the good mail box. I searched in the forum and I think this is file that modify addresses : /etc/postfix/virtusertable. I looked and I have a question There are strange lines, for example : [email protected] and I would like to know if I can delete them. Or ISPConfig will modify the file automatically again? Thanks for your answers.
The virtuserfile created by ISPConfig is fine, so there is no need to change it. If you do not want to have alias lines for e.g. www.mydomain.com, then set the website to external mailserver but do not set the co-domain with empty hostname to external mailserver.
