I've been with DreamHost 12 years this December. Paid as always.
I'm setting up a new domain and it needs emails from that domain, something I've not done. I've tried 3 email programs "Thunderbird, Opera, Pegasus". I've tried many ports that you all have listed.
I cannot send emails.
I can receive emails.
I sent in a support ticket for help and this is what I got.
Hum, I was able to access, send to and from steve@XXXXXXX.com
with no trouble at all.
If there's a specific email address which isn't able to send to
steve@XXXXXXXXX.com. Please provide the email address in question
along with the full bounce back header for review.
Sorry to hear of the trouble.
I sent in the error code, you'd think they'd read it. There is no bounce back!
Worse tech support I've ever dealt with.
