I have just spent a frustrating few hours trying to figure out why my email addresses on Dreamhost were not being forwarded properly. It turns out that dream host has been blocked from my email provider due to spamming issues. Once we finally tracked down the problem, I am advised that this needs to be addressed by Dreamhost. Here is the text I received.
As discussed, TELUS is currently blocking emails from dreamhost.com for spamming our customers.
They need to contact our Abuse team at email@example.com, with a full list of their sending IPs, and (I would imagine) a promise that they will crack down on spam coming out of their domain. Or perhaps there needs to be some back-and-forth on that.
This mailbox is not being monitored. Please do not reply to this email.
Please advise when Dreamhost will address this issue.
