receiving email to non-existent addresses on my domain

[SuSaltz]

I am recently receiving emails in Turkish sent to email addresses @mydomain.com that are not created addresses on my cPanel email. For example, I only have one email address: [email protected]. I am receiving email to: [email protected], [email protected], [email protected], and [email protected].
I updated my SPF to "v=spf1 mx a ptr ip4: (my ip address)/32 a:email.secureserver.net -all"
Is there something else I should be doing? Why am I receiving email to addresses that I do not have created? Below is one of the email headers.
Thank you for any and all assistance.

1st, SPF record has nothing to do with INCOMING emails.

2nd, it's normal that spammers send emails to non-existing email addresses.

You should set the Default Address (cPanel-> Email-> Default Adress) to Discard the email while your server processes it by SMTP time with an error message. Then you never see those emails, they will be discarded.

isn't that option should a way to send a bounce message with a "no such user here" ? right? (and indeed deletes the incoming mail)

But you are still making your server send a bounce message.

am i right @cPRex ?

I always think it's fun when two-year old conversations just get picked up like no time has passed at all :D

Yes, that option still sends a bounce message. This is noted in our docs here: Default Address | cPanel & WHM Documentation

I have an issue. A non-existent email accepts email. Thing is, the rest of non-existent email reject the email with "no such user here".

@normalit_0405 - we need more information on this before we'll be able to help. Can you give us more specific details about the situation you're seeing?

If you go to cPanel-> Email->Default Address what is the setting there?

That's why emails to non-existing address(es) are accepted.

Default Address | cPanel & WHM Documentation

This interface allows you to set up a domain default address (catch-all address) that receives any mail for an invalid email address for the domain.
