SPF misconfiguration (or maybe misunderstanding)

Hi guys,
firstly - I have to admit that I didn't do any search because quite honestly I don't know what to look for - no error logs no nothing just spam keeps coming in :/

What I want - I want to reduce spam as currently I get a lot of awful spams from "myself" ie.

(I suppose you get these as well)

What I did:
I tried to follow the instructions here: https://www.howtoforge.com/hardening-postfix-for-ispconfig-3
I added the TXT record to my NS hosting provider (Cloudflare):

Code:

v=spf1 ip4:185.X.XX.XX -all

Where the 185.X.XX.XX is my VPS IP address used for email hosting.

I followed the part in the article: "SPF Check For Postfix (Debian And Ubuntu)"
apt-get install postfix-policyd-spf-python + did the edits necessary + /etc/init.d/postfix reload and the awful spams from "myself" are still coming.

Any Ideas?

Thanks!

Good day!

I think the potential issue is this: Received-SPF: Permerror (SPF Permanent Error: Two or more type TXT spf records found.)

Which is true - I do have 2 SPF records - one for sparkpost.com and one for my own VPS (185.X.XX.XX), is it an issue in general?
