Linux – Redirect mail from system user account to real email account

emaillinuxpostfixusers

First, I would like to thank you for your time.

I've come to the following situation:

I've got a mail server named mx1.domain.com
This mail server is virtual hosting some domains mail accounts like user1@somedomain.org, user1@someotherdomain.net
As long as the hostname for the server is (and should be so the SMTP Banner is the same hostname as the IP rdl to) mx1.domain.com the default Postfix accounts and server accounts postmaster@mx1.domain.com hostmaster@mx1.domain.com ... are binded to the real hostname, not virtuals.
I've got a simple user for login through ssh, and I've set up my /etc/aliases so the email for all those 'default' addresses go to root user and then I set up root mail to get into my login user instead.

How can I get all those emails, that my system and users send to those default addresses on a real email account? Like one of those that I virtual host.

I assume, that POSTFIX is your local MTA. Thus the following should solve your problem:

echo "yourdestination@domain.com" > $HOME/.forward

Postfix – How to Make Aliases Work for Virtual Domains

I got this awesome link from a tweep and it worked perfectly! If you are looking for the answer, here is my solution. (You need to combine this with the /etc/aliases from my first post, this snippet is only for the virtual domain aliases.)

Configuration

virtual_alias_maps = regexp:/etc/postfix/virtual_users_global hash:/etc/postfix/virtual_users

/etc/postfix/virtual_users_global

# Short version:

/^(postmaster|root|MAILER-DAEMON|abuse)@/   postmaster
/^(bin|daemon|named|nobody|uucp|www|ftp-bugs|postfix|manager|dumper|operator|decode)@/  root

# Or the long version:

/^postmaster@/         postmaster
/^root@/               postmaster
/^MAILER-DAEMON@/      postmaster

/^bin@/                root
/^daemon@/             root
/^named@/              root
/^nobody@/             root
/^uucp@/               root
/^www@/                root
/^ftp-bugs@/           root
/^postfix@/            root

/^manager@/            root
/^dumper@/             root
/^operator@/           root
/^abuse@/              postmaster

/^decode@/             root

Create email accounts independently from passwd using Dovecot and Postfix

Postfix calls these types of accounts Virtual Domains. Dovecot calls them Virtual Users. Virtual domains (and users) are not tied to system accounts.

Postfix can store the virtual domain information in local look-up files or LDAP. Dovecot requires an SQL or LDAP database.

LDAP is a common choice for storing virtual user information because of it's level of support among email software and its fast look up times.

Searching for "postfix dovecot ldap" turns up pages and pages of how-to and tutorial links that will get you started.
