Thanks for the clarifation. I changed it to histomat because I want outgoing mail to appear to come from hai...@histomat.net. However just changing it does not fix my problem. I may have to restart networking. If this works I'll let the thread know. > In this entire thread I have yet to see you simply state what it is > that you WANT or EXPECT. Sorry. I simply wanted to fix the problem that some of my outgoing mail was rejected because of a protocol error. I wanted mail to get to its intended recipient; I expected that to happen. The problem seems to be that Sender: field is empty. > YOU ARE NOT USING DEBIAN SO WE DON'T KNOW! I insist that the Devan operating system I use is identical to Debian except for its lack of systemd.

In network setup during OS installation, if I recall correctly, I'm asked for a) my host name and seprately for b) my domain namer. It is entirely possible that when it asked for my domaiin name that I entered lenin.histomat.net. But this seems unlikelyi because my e-mail system has been working property until just a week ago. > Of course, since we HAVE NO IDEA HOW YOUR OS'S INSTALLER WORKS, all > we can do is guess. If the installer were any different from that of Debian I would have addressed the difference. Devuan is imply Devian without systemd.

You don't seem to know enough to be > running an Internet domain. That is correct. I am not an IT person. My public IP address is indeed 216.239.138.216. I assume it is assigned by my ISP. My ISP is Onnis. My mail service is also provided by Omnis. Would that explain the similarity of the IP addresses? > So, that begs the question of why you think it's appropriate to announce > yourself as histomat.net in your outgoing communications. By "announce" do you refer to my domain name? Are you asking why I use histomat.net as my domain name? That is because it is my domain name. I had my ISP create a simple alias for the domain name historicalmateiralism.info. It has the same IP address as hstomat.net. > Furthermore, we've seen evidence that you're using an outgoing mail relay > (not under your own control) which rejects your outgoing email if you > try to identify yourself as r...@lenin.histomat.net.

I presume that by "outgoing mail relay" you refer to the mail service provided by my ISP. I understand that it will reject r...@lenin.histomat.net because my hostname is not part of my domain name. I have no idea off hand how to test if mail sent from r...@histomat.net will get through. All I can think of is telnet. I don't know whether mail has an option to define the sender.

Or is it going to be 100% guesswork? I cooked up histomat.net and didn't give myself a set of directions ;-). Neither did Omnis. > (Also, what is mail.guardedhost.com? I still never saw an answer to that.) Sorry. I thought I made it clear that this (with port appended) is the address required by my ISP's mail server.
