After upgrade, local domain and secondarymx are empty
Users can't send or receive emails receiving these messages:
From Mail Clients (Microsoft Office):
503 Valid RCPT command must precede DATA
From Webmail, sending to email accounts in the same server:
Error SMTP (550): No se pudo establecer destinatario "example@locallyhosteddomain.comt" (The mail server could not deliver mail to exmaple2@locallyhosteddomain.com. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.).
I tracked why, if these are domains in the same server and the delivery should be local, the files
> sudo vi /etc/localdomains
has only the main domain listed (one line)
and
> sudo vi /etc/secondarymx
is completelly empty

Maybe you should look at
/etc/remotedomains0 -
/etc/remotedomains is also completely empty
I noticed that with> sudo vi /etc/localdomains
listing all hosted domain it can send and recive emials... but...
All sent email to external server is labeled as spam?
What else needs to be reconfigured?0 -
You mentioned you performed an upgrade - was this actually a migration to a new server on a different IP address? If so, that IP address may have had a poor reputation before it was assigned to you, especially if nothing else has changed on your machine.
You will want to ensure that your accounts have SPF and DKIM enabled:
https://docs.cpanel.net/whm/dns-functions/enable-dkim-spf-globally/
or else emails are far more likely to end up in spam.

It was an upgrade over the same server. All programs and configuration was saved, overwritten and recovered by the automated migration program
Some steps in the manual failed and half of the migration was done manually

Did you use ELevate to update the system?

I started with ELevate until after a reboot I was not able to see the start menu to choose the option the tutorial talked about
After that, some Python libraries were messed up and was needed to fix manually
After that, Apaches failed, problem with Exim and some missed domain names
At this point, the only issue to solve is that all sent email from this server is labeled with ***SPAM***

I would check and ensure that all domains have SPF and DKIM records in place.

We ran in to the same problem with email delivery after an upgrade from centos 7 to almalinux 8 via elevate-cpanel https://cpanel.github.io/elevate/getting-started/
After the upgrade /etc/localdomains, /etc/remotedomains and /etc/secondarymx were empty. After testing a few things we decided to restore those files from backup and email delivery started working again. Adding and removing a domain from WHM does not seem to break this again (it simply adds and removes the single domain from the /etc/localdomains file)

1A Support - thanks for that information. I've passed this over to the ELevate team just now.

The ELevate team has created case RE-1348 to address the /etc/localdomains file being modified after an ELevate run. We aren't currently able to reproduce an issue with the remotedomains file, but localdomains is definitely overwritten during that work.
Our team is on that now and I'll be sure to post an update here once I have more details.

Update - this will be fixed in the next version of 126 when that is released!
