I'm new to linux and currently I have inherited a Linux Fedora v14 system that runs a lot of php scripts. I'm having an issue where default email that's sent out is leaving as webserver@mydomin.com. I'm also having issues with that email being delivered. I'm needing help trying to figure out where the default nobody account exists so I can fix the issue. For example I've included a line of my mail log to show you what I'm talking about.

Aug 7 09:00:01 mydomain sendmail[18900]: x77D01YC018900: Authentication-Warning: mydomain.com: nobody set sender to webserver@mydomain.com using -f
Aug 7 09:00:02 mydomain sendmail[18900]: x77D01YC018900: from=webserver@mydomain.com, size=297, class=0, nrcpts=1, msgid=<201908071300.x77D01YC018900@mydomain.com>, relay=nobody@localhost


the area's I have in color and bold is what I'm trying to change.

essentially a dup of https://www.linuxquestions.org/quest...ly-4175658681/

It's still a problem.

Then continue the discussion in that other thread. You haven't responded meaningfully there of late. I've added to it.

I did, sorry just trying to find some help!
