Emails with s that turn into

Hi again:

Thank you again for the previous help. I’m trying to parse the contents of the email (‘text’) after the contents are in $post (‘post_content’) and remove whatever it is in certain places that ultimately get translated either by Postie or by WordPress into “<p>” and “</p>”. I’m guessing it’s some combination of “\n” and/or “\r” but I haven’t been able to figure it out. And I can’t even figure out how to figure it out because by the time I see it in the posted message, it’s already formatted as “<p></p>”.

Could you tell me what the codes are either in the $email(‘text’) or in the $post(‘post_content’) that ultimately turn into <p>s?

Thank you so much for your help.

Second unrelated question: What is the best source to find out all the details of how Postie works with your Category plugin? Is there a README somewhere I can review?
