theocarspot.com, please listen to me for a second.
Here is your problem:
Remote host said: 550 Body From: is missing or empty
This means that the From header is not being parsed properly. There could be several reasons for this.
However, Pattaya City News' main problem seems to be authentication. Besides that, the host also noted that it may be emailing from the wrong domain.
Nowhere in this thread has it been reported that the From header is not being sent. While this *could* cause the same problem, it is not - simply because the From header is being sent, and there are other reasons why this could be. (for example, the webmaster email might be set incorrectly.)
Reporting your problem in another peron's support thread only serves to make them worry. I know enough about YaBB SE to tell you that the two of you are experiencing different problems, and that yours may have to do with the type of mail server you use. (but as yet I do not know enough to diagnose yours.)
If a member of the support team finds the two to be linked, they can post a link to that thread. It, however, makes support very annoying and difficult if we have to discuss the same problems in more than one thread. Especially when you make someone who *isn't* having that poblem think they do. (which will make them follow our advice for you which may not be helpful for them in some cases.)
Remember that none of us get any money for this. From all my work on YaBB SE I've gotten $100 and a book. Which is more than some support people here have gotten... and I've spent hours upon hours on this.
In my real life, I can make anywhere from $35 to $60 an hour... and that's only because I'm still 18. But I do this because I want to contribute.
Don't be so quick to judge.
