In conf it's written exim checks hostname by uname command. uname shows the hostname 'Linux' and not mail. I have hostname 'mail' in /etc/hostname . I presume you didn't mean mail.designman.org as hostname but only mail. So even if hostname shows mail, uname shows Linux. What will exim see?

It doesn't have to be called "mail". > I don't get this. MX record of designman.org points to mail.designman.org. Is mail.designman.org just an email pointer to my domain ip? Can I redirect http://mail.designman.org to http://designman.org or will this cause a port problem for mails? > Now to answer your questions: > 1. How to add users - you have two types of users - system users or virtual > users. System users are created using your OSes user management too (adduser, > useradd, whatever) while virtual users can be name maps in a flat file or a > database (like MySQL, PgSQL, etc) You then tell Exim how to find the virtual > users.
