Just installed sendmail from ubuntu apt repo
when I ask the status of the freshly started emacs I see.

I'm sorry to through so much data out there but I hope someone is
willing to go through some of it. As must be obviouse I'm in dire
need of some coaching pointers URLS etc.

all seems to be pointing to something pretty badly wrong with submit.cf

I've included the current submit.mc and sendmail.mc.

m4'ing was done after conclusion of editing

I mainly used these pages to try to get started

https://netcorecloud.com/tutorials/install-sendmail-server-centos-7/
https://mailoutgoing.com/support/mailrelay/sendmail.html
https://www.oreilly.com/library/view/linux-network-administrators/1565924002/ch18s08.html

I didn't find much in those about editing submit.mc but took a few
tips seen in the submit.mc below startup messages.

`emacs` or `sendmail`?

Well, the reason is written on the tin. But you need some familiarity
with Sendmail to understand what the tin is saying.

The MSA daemon(_port) can't bind to the address (that it's configured to
use) because the "Address (and port are) already in use".

/From/ /a/ /quick/ /glance/ at your submit.mc and sendmail.mc files, it
looks like both of them are trying to bind to port 25 on 127.0.0.1.
That's a conflict and won't work. ;-)

I am not an expert, but according to the documentation, the default is
that SM listens to 25 and 587 (submission).

https://www.oreilly.com/library/view/sendmail-4th-edition/9780596510299/ch17s08s35.html

FEATURE(`no_default_msa') disables listening on 587.

If you have DAEMON_OPTIONS(`Port=submission,...) enabled, this might be
a conflict, so try to enable FEATURE(`no_default_msa') or disable
DAEMON_OPTIONS(`Port=submission by adding dnl at the beginning (m4
Syntax).

Then service sendmail restart (this creates the cf file in Ubuntu and
Debian).

Is this the only MTA that you are running?
Could be postfix, msmtp, msmtp-mta already is installed and running and
those already bound the port.

You can try with "telnet 127.0.0.1 25" and look at the output to guess
or using "lsof -i", "netstat -lnp" or "ss -ap" to determine what is
already bound to port 25.

Yes I see your point. It does look wrong.

Yes, its the only one

thanks.

All posters; thanks for taking the time to help and for giving helpful
input.

I'm going to retrench a bit and try installing sendmail from source
version 8.17.1.26 ... Hopefully I will learn enough in that process
from the lengthy documentation (whatever I am able to understand of it
that is), to be a little more confident about what I'm doing.

I'd like to install the executables in a trial place.... I know there
is a way to tell `configure' or `make' about a --prefix=some/trial/dir.

Can anyone say how that is done using sendmails `./Build' command?

I *HIGHLY* recommend the README and cf/README files (namess from
memory). At least skim them so you have a vague idea of some things
you'll recognize when you run into them again. You might even want to
skim them twice, once to have an idea where something was and again to
skim ~ read for content while referencing things you now have an idea
where they are.

I also strongly recommend the Sendmail Installation and Operations Guide
at some point.

Those few files should get you started with a simple serviceable
configuration.

Also, please feel free to ask questions. You can also email me directly
if you don't want to discuss things in public.

I think that's covered in the README file in the root of the (extracted)
source code directory.
