With the 2.4.17 this issue is still there. It seems that the reporting/includes/class.mail.inc is still not fixed. With every update the new file is overwritten and we are back to the same issue.
When I replace the core file with the change information as indicated below it will send the emails and attachments as expected.
"I have found the solutions by changing all the \n code in the file to \r\n and it works on both PHP7.4 and PHP8.0
Emails are now sending and displaying correctly when sent from FA.
\r\n is for a new line in windows as for \n in the new line in Linux.
Use \r\n instead of \n for your implode -- explicitly specifies CRLF as the line terminator."
Why are we keep on having the same issue irrespective of the PHP it is set on?
Is no one else have the same issue?
