Problem sending E-Mail from a website via php

I am trying to send an E-Mail from my site, suanhacky.org. the E-Mail address is webmastera@suanhacky.org. I get the following error trying to send a E-Mail there...

When I send an E-Mail to my regular address it works fine, but I get the above error when I send to any @suanhacky.org addresses. The E-Mail does exsist and works cause when I send a E-Mail out via Outlook express to it I get the E-Mail no problem.

here is the code I used to test when I first saw the problem

Any help on resolving this problem would be greatly appreciated

Could be a spam blocker, I guess. Are these email addresses on the same host?

the webmastera@suanhacky.org E-Mail address is a forwarding E-mail address created in yahoo MyDomains it goes to my reqular E-Mail address which is a road runner E-Mail address

If roadrunner's using SpamAssassin or something similar, there could definitely be a spam blocking problem. For example, I recently had to upgrade SpamAssassin on my mail server because there's a problem with Message-IDs in the headers under some circumstances. This'll only matter, in many cases, if you've got other factors causing a message to be flagged for spam, which could definitely be more likely to happen from a script than from a bona-fide mail client. I guess this could also be the case if the host of suanhacky.org is running filters, since it's possibly the fact that the mail's going through a script that's flagging it (assuming this is a spam issue).

When I send an E-Mail from my road runner account to any @suanhacky.oeg E-mail address it goes through fine with no problem

... hmmm..... i would guess on a error in the setup of php ?!

Right, ChornJr, but when you send mail from a script, you're adding a whole new potential set of spam flags because the mail's being relayed. Furthermore, you're setting the mail up to have more than one Message-ID because of the relay, and this is precisely the problem I ran into, which was fixed in a recent version of SpamAssassin. That you can send mail successfully one way indicates that there's not a problem with the mail account but rather that there's one with the other way you're sending mail, which in this case is a script. What I'm suggesting is that whoever's hosting suanhacky.org is running filters that don't trip when you send mail by a conventional method but that do trip when you send mail via a script. And I'm proposing that you ask your host if that could be what's happening. Telling me that you can send mail by a conventional method without problems after I've given you a plausible other explanation doesn't get you anywhere.

I will check with them
