php.net / Mosso

Hi,

I have my personal e-mail - [email protected] - hosted by Mailtrust  
which is owned by Rackspace (aka Rackspace Noteworthy). I was having  
trouble sending mail to my [email protected] e-mail address from  
Mailtrust hosted e-mail accounts and contacted their support team to  
look into it; specifically their SMTP server was rejecting the e-mail  
because it said [email protected] didn't exist.

Hi David,

Thanks for that update. The information helped out greatly.

The nature of this error message is because Noteworthy checks locally  
for a domain before referring to MX records. If the domain is found  
from within Noteworthy, it does not use the MX record values.  
Furthermore, if the domain is found, but the mailbox is not, then the  
message will bounce in the manner you posted.

That being said, the domain php.net does exist within Noteworthy, but  
that mailbox is not assigned to it. The domain is hosted by one of our  
divisions, MOSSO, and I will contact them to try and remove this  
domain, or at least straighten this all out for you so you can send to  
them.

Hi David,

I just spoke with a representative from MOSSO and he will be getting  
in contact with the account in question to work on removing that  
domain from Noteworthy. Please allow around 30 minutes for the changes  
to happen, and possibly up to another 15 for the changes to fully  
propagate, and then you should be able to send to this user just fine.

I have asked them why the php.net domain existed on their system:

Hello David,

Unfortunately, I do not know how that domain got added to MOSSO, or  
who was on the account that added it, but one of their accounts added  
that domain somehow, and it somehow got added to Noteworthy.

Perhaps it may be something you might want to run by your contact over  
at php.net to let them know that there may be some security issues  
going on there.

So yeah, are any php.net domains actually hosted by Mosso and if not,  
is this something that needs looking into?
