Spam report: BASE64_LENGTH_79_INF

[bvelastegui]

First of all thank you very much for your work.

I comment that when sending emails with an attached pdf document mailtrap.io indicates this in your spam report:

Pts	Rule name	Description
2.0	BASE64_LENGTH_79_INF	BODY: base64 encoded email part uses line

To generate the PDF file I am using mpdf.

I did not find information about it and for this reason I go to you.

Thank you very much!
