Okay Ray, I ran the test and got a 0! :) lol.
I attached the screenshot and hopefully you can help me decipher where to look.
I have tried the following for each error message:
SPAM ERROR: Missing blank line between message header and body - 25 points
1. Added HTML returns <br /> (in code, which I know would not help) to each of the Email templates
2. Tried looking for /r/n new lines but could find none that seemed to matter.
SPAM ERROR: Missing To: header - 16 points
1. Added " " . (WAGLOBAL_Registration_Email_TO) . " "; to the $MailTo variable (line 5 of my WAUE_users_Registration_1.php file.
SPAM ERROR: BODY: Weird repeated double-quotation marks - 28 points
The people who are not receiving their email are the aforementioned email account types and registered when using version 3.0.6 of UE (after upgrading). There were apparently no problems prior using 3.0.5.
Thank you Ray for the suggestion. It was alarming to see my score of 0.
If you can help me fix at least the 28 pointer, I would be (again) extremely grateful.
