Hi @Grashee ,
please make sure you've installed all required php extensions:

sudo apt-get install php*-imap php*-mbstring php*-mcrypt && sudo apache2ctl graceful

..and check #14 and #30 as well. Feel free to reopen this issue if you still encounter the same problem :)

Best regards

i have this issue too with my macOS, php@7.2, valet.
in terminal its ok but in browser have this issue and it says imap_open is not a function.

the solution:

sudo brew services restart php@7.2
sudo brew services restart nginx

im trying without sudo, nothing changes.

This constant is defined by php-imap, php-imap is required as dependency.
@Webklex However my development environment has no php-imap installed, might be good to build in some check?
