Cant send / recieve all email

[Ciaran-IRL]

I signed up to a message board and I am waiting on the actvation although when I checked the logs I am getting

"RCPT TO:<nobody@proboards21.com>" from mail.proboards.com [67.15.247.140] was: 550 5.7.1 <nobody@proboards21.com>... Relay$
2007-09-20 16:45:54 H=proboards21.com [64.246.60.110] F=<nobody@proboards21.com> rejected RCPT <admin@picsonprofile.net>: S$

Any idea what this means and how it can be fixed?

here is my log here

This has been discussed on this board a few times. One thing you may want to do with the forum script is set a reply-to address. Additionally, to avoid having email sent as nobody@, set up SuExec/SuPHP so these scripts do not run as user nobody, but rather as the user name of the account in which the script resides.

I dont think you understand what is happening that is the email that was sent by the server for a message board activation its not my server, the email is coming from proboards.

Sorry about that, my mistake.

In WHM -> Service Configuration -> Exim Configuration Editor, do you have the following setting selected:

** Use callouts to verify the existence of email senders. Basiclly, exim will connect to the mail exchanger for a given address to make sure it exists before accepting mail from it.

If so and that email user isn't reported as existing - it would explain why the message was not delivered.

yeah that is ticked.

yeah that is ticked.

If that nobody@ address does not exist according to that remote mail server, then the message will not be delivered according to that setting. The purpose of the setting is to curb spam coming from fake email addresses.
