Steps to reproduce the issue

• Install nighlty build Joomla_5.3.4-dev-Development-Full_Package.zip
• Enable 'Log Almost Everything' and 'Debug System'
• Home Dashboard > Server > Send Test Mail
• Check administrator/logs/everything.php

Expected result

The log entries for a successful e-mail delivery have the priority INFO.

Log entries for e-mail errors have Priority ERROR, e.g.

2025-08-22T04:03:49+00:00       ERROR 192.168.65.1      mail    Error in Mail API: Connection failed. Error #2: stream_socket_client(): Unable to connect to host.docker.internal:7024 (Connection refused) [[ROOT]/libraries/vendor/phpmailer/phpmailer/src/SMTP.php line 412]

Actual result

All log entries for sending e-mails have the priority ERROR. See everything.txt. This may confuse adminsitrators if they are not the receiver of the email and therefore not sure is there a problem or not.

System information (as much as possible)

Tested with JBT.

Additional comments

• First found with #45958
• This issue may have the lowest priority.

If there really are problems with the e-mail, then these should of course be logged with the priority ERROR. With JBT:

• You can read the emails with http://localhost:7004
• Simple change change SMTP port from 7025 to e.g. 7024
