Re: Spam assassin custom rule to block PDF files having Urls.

Hi,

I wrote the rule below.

uri SPAM_1Jul2022_uri_1 /https?\:\/\/t.ly\/8R_H/i
describe SPAM_1Jul2022_uri_1 Email containing above words
score SPAM_1Jul2022_uri_1 11.0

It can NOT detect this url inside the PDF file.

But, if I just write it to the mail body, It can detect it.

I need a rule that can detect urls inside a PDF file. Can you guide me?

Hope to hear from you.
