So my smtp php mailer is showing that the message was successfully sent but in reality it's not. I am now using email from the same domain that Synchro suggested because I was using gmail please have a look here and had issues with it and php mailer was showing error but after switching to mail from the same domain actually it is showing sent but I am not receiving any email. So I went to my email logs and found this.

It's not quite clear what you're doing, but at a guess it looks like you are sending from a gmail address without sending through a gmail server, and that will always fail SPF checks, because google doesn't allow that. It's nothing to do with the submitter's address, but the email server that you send the message through – if it's not smtp.gmail.com, then you can't use a gmail address as your from address.
