Logwatch return email address

[wolfrR1der]

This is probably an easy on that I can't seem to find nor can I find search results for it.

We exported a CentOS8 VM to use as another, similar server and for the most part this works fine. However there's one little annoying thing that I can't find an answer to. When Logwatch sends out it's email the return address is for the previous server. The email shows it's from Server1@company.com but it's the report for Server2.company.com. Note that Logwatch sends email to "root" and root's email is then forwarded via alisas to me.

Where do I find this address at? It's not in the Logwatch, not in aliases, not in postfix's main.cf.

No experience with logwatch, so this is just guessing: did you change the hostname?

[lightman47]

I suspect it's from the machine name itself. Did you change it to server2 after you cloned it?

What shows up when you sudo hostnamectl in server2?

[wolfrR1der]

Yeah, hostname was changed. After reboots it reports the correct hostname. When I just ran the "hostname" command it reports the new hostname. I am at a loss.

[lightman47]

does the configure section in this help you?

And you don't have "mydomain =" in /etc/postfix/main.cf or a line in /etc/postfix/generic that tells it to translate e.g.

@thisbox.company.com @company.com
