Proxmox Mail Gateway rejections from some domains but not others, aka “my last post if full of shit”, sort of.

computers, dovecot, email server, Linux, Postfix
It is really hard to test some of this stuff out.  In my last post I did certainly cover the effect but I thought I understood the cause as well.  That is not the case, so I was full of shit, so to speak, and sort of. The problem was, if my customer sent or forwarded from some domains both related to one company the emails were rejected.  A reject email was sent back to the originator of the email. I thought this had to do with configuration of the Proxmox Mail Gateway (PMG).  That was partially correct.  Those things I spoke about in my previous post were problems, and I did correct them, and that is a good thing.  There was more wrong.  I needed to resolve that as…

Who am I

Asterisk, History, Linux, Postfix, Virtual Web Servers
My experience with desktop computing goes back to the early years of PCs.  I began working with desktop computers in the early 80s.  I worked on some terminal based systems in the USAF and in college, yet any computing interest never took hold.  They seemed costly (expensive) and impersonal.
