Information about bug

Good day I'm unable to send invoices via email to customers directly from the system. It seems to work sometimes when i pick the option to physically attach the email however I would like to be able to pick the attachment automatically.

When i check my error log its says email sending failed. I have attached the error log in the log output section.
