Email issue: long-existing account now bouncing!


I have been a dreamhost customer for 3.5 years, and have had this email address all that time.

I have two support tickets open at the moment, and they have been for 7 & 8 hours, but still no reply.

I know the usual target is 24 hours but this is an urgent issue, has been marked as such, and I normally get responses within a hour or so.

I’m sorry to have to inform you that your message could not
be delivered to one or more recipients. It’s attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

IMHO this problem is in your (postfix) end of the system, not in the DH end.

It looks like your mail server is rejecting the incoming message.
