Checklist

  • Can you replicate the issue on our v5 demo site https://demo.invoiceninja.com or Invoice Ninja? Haven’t tried
  • Have you searched existing issues? yes
  • Have you inspected the logs in storage/logs/laravel.log for any errors? yes

Describe the bug

Currently Invoice Ninja adds pdf attachments as MIME type application/octet-stream. I have an issue specifically with the Scaleway TEM provider as they enforce a MIME policy which prohibits octet-stream. Couldn’t this be set as application/pdf? It would be fitting in regards to the actual content.

Steps To Reproduce

  1. Try to send invoice to mail provider that doesn’t support application/octet-stream
  2. fails

Expected Behavior

As the attachment is a pdf file MIME type should be application/pdf

Hi,

I suggest asking in a discussion on GitHub.
