The ISP that u are sending the e-mail to is rejecting you.

I had this same error message from one domain. I finally got through to the support guys via the html support/problem report page. They fixed it once, and it appears to work again. A couple of weeks later, i got the same error again. I appended to the orig problem report that this problem is back. They said they removed/fixed the cause.

issue a problem report to the destination ISP. They probably installed a new SPAM system that still has bugs.

has been in the queue too long''?


Yes it does:
