Remapping root account email

daveginorge · 12-21-2015, 03:07 AM

Hi All
Postfix mail server.
I have mapped

Quote:

root@mydomain.com to fw@mydomain.com

but when sending emails it sill has root as the username eg

Quote:

root <fw@mydomain.com>

is there a way to map out the root username, if so how.
Thanks in advamce

Code:

root <fw@mydomain.com>

That is not the username, but the name. When you send mails from fw@mydomain.com, you'll need to specify 'Some Name <fw@mydomain.com>' or change the name for fw/root.

An email client will take whatever name it can when that is not properly setup.

Hi Robert
Actually that is the username, it's being sent from the root account, so the name & username are the same in this case. I was just asking is it possible to map the root part to another name when sending emails from the root account.

You can do this:

Code:

echo 'Some message here' | mailx -s 'My subject' -r 'Some name <fw@mydomain.com>' 'somebody@example.org'

mailx needs to be installed if you dont have it, 'somebody@example.org' is the person who you are writing to. Basically you need to control the 'From' header when sending a mail and you can put whatever you want.

The system administrator can define email aliases in the file /etc/aliases. This file contains lines like root: cwd@mailhost.example.com, /root/mailbox; the effect is the same as having cwd@mailhost.example.com, /root/mailbox in ~root/.forward. You may need to run a program such as newaliases after changing /etc/aliases.

Note that the workings of .forward and /etc/aliases depend on your MTA. Most MTAs implement the main features provided by the traditional sendmail, but check your MTA's documentation.
