error message with PHP 7.4

[Dan33l]

Hi,

The documented requirement is PHP 7.3 or higher. When i run utils/fetch_reports.php with PHP 7.4 (Ubuntu 20.04) i am getting the following error message :

dmarc-srg [error]: ErrorException: The behavior of unparenthesized expressions containing both '.' and '+'/'-' will change in PHP 8: '+'/'-' will take a higher precedence in /opt/dmarc/classes/Mail/MailMessage.php:111
Stack trace:

#7 {main}
Error: The behavior of unparenthesized expressions containing both '.' and '+'/'-' will change in PHP 8: '+'/'-' will take a higher precedence (-1) 

All is working fine with PHP 8.1 (Ubuntu 22.04).

If lower requirement is PHP 8.0 i can propose a PR to modify the documented requirement.

Note : I had to install the mbstring module for PHP. I could add this dependency too in PR.

Hi @Dan33l, This issue was already fixed, see the details in #114

Oh, I forgot to add it to the dependencies. I will do it. Thank you for your report!
