Upgrade to Laravel 7.x

[schmeits]

Hi there,

May I ask when you're planning to upgrade to Laravel 7? I see there will be some errors because of some missing Symfony components (e.g. Symfony\Component\HttpFoundation\File\MimeType\ExtensionGuesser)

Found a quickfix for my project (fetching attachments from a mail in a mailbox)

in file src/IMAP/Attachment.php replace line 298:

return ExtensionGuesser::getInstance()->guess($this->getMimeType());

by

return MimeTypes::getDefault()->getExtensions($this->getMimeType())[0] ?? null;

with the correct uses ofcourse

Just ran into this problem too, schmeits his fix works but editing vendor files is not really a way to go on production environments.

Same issue,
Error
Class 'Symfony\Component\HttpFoundation\File\MimeType\ExtensionGuesser' not found..

Trying fixing from vendor for now, thanks @schmeits

Same issue, however since we are using laravel 7, I opted to just replace my extension code with Str::afterLast($attachment->getName(), ".")

Thanks for your suggestions. I've added a fix to support all laravel versions including 7.x.

Best regards,
