Root mail redirection

English Network/Internet
#1

Hello all!

I’ve used Yast’s Mail Transfer Agent (MTA) module to configure the redirection of the root’s mail.

In the MTA module I’ve only filled the “Forward root’s mail to” field with my e-mail address.

The problem is that in my e-mail account I receive the following:


This is the mail system at host SERVER01.lan.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                   The mail system

<my_mail@my_domain.pt> (expanded from <root>): host
    mail.my_domain.pt[MY.IP.ADR.ESS] said: 550-Verification failed for 
    <root@SERVER01.lan> 550-The mail server could not deliver mail to
    root@server01.lan.  The account or domain may not exist, they may be
    blacklisted, or missing the proper dns entries. 550 Sender verify failed
    (in reply to RCPT TO command)

And attached comes the message that I should receive.

Here is the mail as seen by the mail command executed as root:

Any ideia of what’s wrong?

Thank you.

I think, unless your are using virtual domains, the easiest way to get that
done is by using /etc/aliases (see the first line for root’s redirection
mail to another system user).

I’ve got there:

The “\root” will make sure that email is also delivered to the

root-account, but also forwared to the user “joe”.

#root: joe, \root

root: hpc02

Where “hpc02” is my common user.

After making any change in this file, run “postalias”… mmm, better read me
manual (“man aliases” and “man postalias” just to be sure).

A 550 error, as the message is telling you, indicates postfix cannot
recognize the sender so returns the message.

Maybe you forgot to run any “postfix reload” to force Postfix to re-read the
configuration files and lookup tables? :-?

P.S. Be careful with yast2 modules because after using them to configure any
service you have to take care about not editing manually the files of that
service, as they can easily get “messed-up”.

Hello Camaleón!

Thanks for your reply.

In my /etc/aliases file I have the following:


# The "\root" will make sure that email is also delivered to the
# root-account, but also forwared to the user "joe".
#root:          joe, \root

root:   my_mail@my_domain.pt, \root

I ran the “postalias /etc/aliases” command and also the “postfix reload” command but I still get the same message.

Are you delivering to a non-local account?

Then you have to setup postfix to go-out with a real e-mail address, not
a “fancy” one. Your mailserver located at “my_domain.pt” is rejecting
that “fancy” address :slight_smile:

Take a read into this doc:

Done! Now I receive it on my external mail account.

Thank you very much!
