I configured several servers from different IPs to email all their log messages to one certain PC.
I already changed in all Boxes in question via /etc/email-addresses the from-address part of mails to send, but on the receiving PC (within kmail) in the "From" column I nevertheless get only username "root" displayed (of course).
So how can I change the from-address-FORMAT sent by the sending exim servers from
"USER <USER@DOMAIN>"
to just
"USER@DOMAIN".
Anyone has an idea??
Thanks
Chris

Well you can configure the outbound email to be whatever you want it be when its generated. Where are the emails being generated(application, PHP, etc.)

This is the way to do it, there are places where you can hard code the from address depending upon the way it is sent but it is hard to embed BASH variables such as $HOSTNAME into them.

Thank you for your prompt response (other than me...)
The mails are generated by my own scripts or otherwise mainly by cron or other system services. I understand that it's possible to set a "From:..." header in my own scripts, but how can I do this for all the other daemons?
EDIT: Hardcoding is ok, anything is better than just "root" as sender name for all hosts in the From column of kmail.

There are some MTAs that have plugins that allow you to hardcode a from email address, but any application that is passing a from address will overwrite it. The best practice is to generate the email you want it to be delivered. You can use things like procmail or postfix and try and rewrite your message headers but that can be a bit tricky. There are a few guides on re-writing message header on google. First figure out what MTA you are using, such as postfix or sendmail and then do a quick search.

Here is one for postfix.

The MTA is exim on every host. Sorry for not stressing this enough in my first post.
And I know, it is not only tricky but usually quite a pain to go into MTA's config details, that's why I made this post, hoping someone knows a SIMPLE answer - was probably a little bit naive.....
Thank you for your help anyway.

If you send using mailx (which will then send via your exim MTA), you can use the -r flag thus

I didn't check this thread for a while, so I did not see your post.

The problem are not mails sent activly via a MUA, but all the mails sent by system services. They all arrive here with sender address "root", and I wish to make it a little bit more clear in my receiving MUA, without filtering each sending host's mails to a separate folder. So it really should be something to configure...

Here is the exim documentation for rewriting. This should give you what you need to get there, if you have specific questions about the implementation let us know.

thank you very much, I think, this is what I was looking for.
When I was searching in several manuals for exim I found on the net, what I found always made me think I had to read a whole book to find out what to do to rewrite a single header line. But THIS looks reasonably simple so I can understand it with my existing knowledge right away.
If still it is too much for me I'll come back here...
Thanks again.
