Receiving spam from my Own Server

You can see this in the source of the spam email.
Try to add or edit your SPF record if they are not being flagged as spam..

Hi Ron-E! Thanks for replying to my post. I'm not exactly sure to be honest. I don't really know how to read these email headers. I thought it did, but even Spamassassin is showing a different IP address as the receiving IP as is listed at the top of the header (received: by 10.194.xxx.xxx). So I don't even understand where SpamAssassin is getting the IP address of 41.60.XXX.XXX.

I have copy and pasted the email original message below so you can see. I'd really appreciate any help you can provide. I slightly modified the below email to mask some of the IPs and my server domain name with MYDOMAIN.com and MYEMAIL@gmail.com (which is the email address my web server forwards contact@MYDOMAIN.com to).

As for the SPF record, I have this set on my MYDOMAIN.com DNS. It's listed as this:

TXT @ "v=spf1 a mx ip4:104.131.XXX.XXX ~all"

I think these are all setup properly and everything appeared to check out find when setting up the email server. And this server has been running for about a year now with these settings. I just recently noticed these spam emails coming from MYEMAIL@MYDOMAIN.COM to MYEMAIL@MYDOMAIN.com because of a gmail filter I setup, which says to NOT PUT IN SPAM folder if email comes from @MYDOMAIN.com. So now these spam emails are showing up in my inbox. It's not a big deal, I can just delete them, but I'm just curious if I have something setup incorrectly on my server allowing spammers to use my email server to email me spam. I'd like to prevent/stop this. Thank you!
