I am using a simple php contact form on one of my clients websites.

 

Problem is - his mailbox won't accept it.

 

I think last time I had a problem someone mentioned changing permissions on the email server.

 

Here is the error email I received:

 

This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more ofits recipients. The following addresses failed:   <********.com> SMTP error from remote server after RCPT command:host mail********.com[***************]:550 Blocked.

I have had this problem with contact forms before and its one of those areas I like to avoid looking into. However I need to learn what the issue is sooner or later as its becoming a common problem..

 

I am sure many of you here know what is going on, thankyou.

Ahh.. I checked out the error: "550 - The requested command failed because the user’s mailbox was unavailable (such as not found)"

 

Since its a new business he might not have the email address yet. Sorry for my laziness feel free to delete this thread (although it may help others).
