Issue External Email Stopped Working after Upgrading to Plesk Obsidian 18.0.70 Update #2

Server operating system version

Rocky Linux 8.10

Plesk version and microupdate number

Plesk Obsidian 18.0.70 Update #2

Everything has been working great until the latest update.

I've verified the email account settings using a desktop client and re-entered the details into Plesk.

All Plesk emails should be coming from [email protected], but now they are being sent from [email protected], and when they are sent from Plesk it's from [email protected]

When I log in to SSH as root, an email is automatically sent using a script, but it has stopped working as well as Plesk notifications and password resets.

Examining the mail log, it appears that it's attempting to use the server hostname in the HELO and envelope.

My /etc/msmtprc

passwordeval /usr/lib64/plesk-9.0/msmtp-pwdeval

When enabled
"Allow user scripts to send mail through this SMTP server (using the specified username and password)"
Doesn't allow users to access or use the relay and I see their [email protected] in the error logs with " smtpstatus=550 smtpmsg='550 5.7.60 SMTP; Client does not have permissions to send as this sender' errormsg='the server did not accept the mail' exitcode=EX_UNAVAILABLE"

There needs to be the ability to set the from email address and domain name.

Everything needs to be sent from [email protected] to properly authenticate and pass email security, SPF, DMARC, etc.

I've uninstalled, reinstalled the External SMTP, and even rebooted the server.

Any suggestions for fixing this would be appreciated.

Additionally, maybe relevant info:
The only other operation on the server was that I upgraded MariaDB from 10.6 to 10.11, and I encountered a PHPMyAdmin error. This error led to the complete removal of PHPMyAdmin, along with the database and user, and the subsequent reinstallation of it, which corrected the problem.

To get back to the operational level, I had to modify the /etc/msmtprc

I had to hard-set these values. (Which should be available in the Plesk Panel under settings!! )

• from email
• allow_from_override on
• domain

For my login script, I had to modify it to:

ip_address=$(who am i | awk '{print $5}' | sed 's/[()]//g')
server_hostname=$(hostname)
date_time=$(date)
org_name=$(whois "$ip_address" | grep -i "Organization:" | awk -F':' '{print $2}' | tr -d '\n' | xargs)

{
echo "From: [email protected]"
echo "To: [email protected]"
echo "Subject: Alert: Root Access from $ip_address on $server_hostname"
echo
echo "Root Shell Access Detected"
echo
echo "Date: $date_time"
echo "Server: $server_hostname"
echo "IP: $ip_address"
echo "ISP: $org_name"
} | msmtp --read-envelope-from -C /etc/msmtprc [email protected]

For Plesk Notifications coming from psaadm, I had to add the subdomain to my Exchange server, create a distribution user of [email protected], and add it to the Send As permissions list of [email protected].


I thought Plesk was supposed to save me time, but another afternoon was spent entirely on something that should be a few clicks. Do better, Plesk.
