UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support System-generated Emails Bouncing Back....

Okay, this is a really weird issue. All of the system-generated messages, including registration emails, PM Notifications, etc. are bouncing back to the main administrator email address.

The error being returned is:

"553 sorry, your mail was administratively denied. (#5.7.1)"

More details:

"while talking to relay-hosting.secureserver.net:
>>> MAIL From:<*removed*@gmail.com> SIZE=1064
<<< 553 sorry, your mail was administratively denied. (#5.7.1)
501 5.6.0 Data format error

At first I thought it was a problem with just registrations, then PM's started happening. Here's the REALLY weird part - today a new user registration message went out to the admin email address, saying there is a new user in the queue. However, the Admin did NOT get that original message... instead, he got a bounce-back message, which came to the same address that the original message was supposed to go to!

So, it seems that it's definitely a problem in the system somewhere... and this has only started in the last couple of days - it's worked perfectly since the site opened in Februrary....

Any ideas?

5.7.1 is normally going to be the Relaying Denied error. So, I'm guessing that your host has made some changes to their mail configuration and your site isn't being allowed to send email through their server.

I'd contact your host and give them the error and see what they suggest.
