Hello, there is no official 7.0.5 version. Unless you meant 7.0.3

Please try updating to 8.0.1 to see if it resolves your issue.

Generally, a 500 error refers to your server. Possibly check with your hosting company too.

Sorry. my mistake. It is 7.0.3. The mail function worked fine with 7.0.3, but not with 8.0.0.

And I just upgrade to 8.0.1 without luck.

The server i host is my own CentOS 7 server.

Hi,

Error 500 means problem on the serveur side.  
Could you send us the php error log of your server ?

Now i found the problem that for new system to work, I have to upgrade to PHP 7

In PHP 7 we additionally get the ?? operator which rather than indicating extreme confusion which is how I would usually use two question marks together instead allows us to chain together a string of values. Reading from left to right, the first value which exists and is not null is the value that will be returned.

// $a is not set  
$b = 16;

echo $a ?? 2; // outputs 2  
echo $a ?? $b ?? 7; // outputs 16  
This construct is useful for giving priority to one or more values coming perhaps from user input or existing configuration, and safely falling back on a given default if that configuration is missing. It’s kind of a small feature but it’s one that I know I’ll be using as soon as my applications upgrade to PHP 7.

Great so your solution has worked by upgrading the server php version to 7.0?
