**Your software**  
My Mautic version is: 3.1.0  
My PHP version is: 7.2

**Your problem**  
Amazon SES API is not working… When I change to ‘sendmail’ or ‘Amazon SES SMTP’ the campaigns work and emails are sent…

These errors are showing in the log:  
[2020-09-14 17:08:12] mautic.NOTICE: Symfony\Component\Debug\Exception\FatalThrowableError: Call to undefined function bandwidthThrottle\tokenBucket\util\bcsub() (uncaught exception) at /var/www/vhosts/mautic.webpros.marketing/httpdocs/vendor/bandwidth-throttle/token-bucket/classes/util/TokenConverter.php line 80 while running console command `mautic:campaigns:trigger`    
[2020-09-14 17:08:12] mautic.WARNING: Command `mautic:campaigns:trigger` exited with status code 1

Steps I have tried to fix the problem:  
Downgrade php 7.3 to 7.2, restart server, delete cache folder…

I searched online and found the solution by running the following command to make sure to have bcmath installed in all php versions…

sudo apt-get install php7.1-bcmath  
sudo apt-get install php7.2-bcmath  
sudo apt-get install php7.3-bcmath  
sudo apt-get install php7.4-bcmath

After that I also had to select email queue in email configuration and set 36 emails per 1 second (as my Amazon SES limits…)

Hope this works for people experiencing the same issue…

But now I´m getting the following error:

Hi,

I have develop a plugin to Mautic 5.

You can try in: [GitHub - pabloveintimilla/mautic-amazon-ses: Mautic 5 plugin, provides Amazon SES as an email transport and callback to process bounces](https://github.com/pabloveintimilla/mautic-amazon-ses)

Regards!
