Spam assassin custom rule to block PDF files having Urls.

[Indunil Jayasooriya]

Dear List,

We get some PDF files. When we open them there is a link inside the PDF
file. We don't need these since these urls may be harmful.

Here's one Url that the PDF file contained.

https://t.ly/8R_H

Can we block these with Spam Assassin?

If so, how to write a custom rule for it?

Below Url has some instructions.
