Whats this

Once an add is posted I get a few rows of this message at the top of the screen. Looks like classifieds has a problem with the mail. Any ideas what a 551 Bad recipient is. Thanks in anticipation.

Warning: mail() [function.mail]: SMTP server response: 551 Bad Recipient in [path]\classifieds\pp-inc.php on line 3364

Warning: mail(): SMTP server response: 551 Bad Recipient in BLAH BLAH

That's a message from your server.* It indicates that the PHP installation on your web server will not send the email because it considers the email address to be invalid.

I think you need to contact your hosting provider and show them this error message.

BTW, is it a Windows server? Maybe your host has certain email domains blocked etc but as noted it is the server thats considering the email passed as invalid.

Hi Chuck, thanks for a quick response. Yes, its a dedicated server and I'm sorry to say that it is windows. That said, VBulletin and wordpress installations on this same server send out mails all day long. How might Classifieds be doing it different so as to get the error.

Thanks in anticipation

well check your server error logs. see what they say. all I did was do a internet search on that error and it comes up with that responce I gave. seems to be a server issue from what I am seeing.
