**Your software**  
My Mautic version is: 2.15.1  
My PHP version is: ea-php72  
smtp: Sendgrid API

**Your problem**  
My problem is: Evertime I try to send email I get a 500 error,  
On test and trying to send myself an email.  
These errors are showing in the log: It makes a new one like this everytime I try to send.  
[2019-08-26 16:37:41] mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\UndefinedFunctionException: “Attempted to call function “iconv” from namespace “Symfony\Polyfill\Mbstring”.” at /home/dowellhosting/public\_html/email/vendor/symfony/polyfill-mbstring/Mbstring.php line 114 {“exception”:"[object] (Symfony\Component\Debug\Exception\UndefinedFunctionException(code: 0): Attempted to call function “iconv” from namespace “Symfony\Polyfill\Mbstring”. at /home/dowellhosting/public\_html/email/vendor/symfony/polyfill-mbstring/Mbstring.php:114)"}

Steps I have tried to fix the problem: Increased PHP memory, rebooted server
