My connectivity provider does not provide an outgoing mailserver, and I'm having problems sending email (SMTP) via Dreamhost, i.e. to mail.MY-DOMAIN.com, hosted at DH.
I've read the instructions at http://www.dreamhost.com/hosting-features.html
but authentication is being refused.
How do I need to configure my mail client to solve this problem? I've tried telling it to try using my "panel" DH password when querying mail.MY-DOMAIN.com, but to no avail.
In short, what is actually required to authenticate gateway SMTP access?
My connectivity providers tell me they aren't the problem, and I believe them, because my mail client is getting told that authentication at the DH end is failing.
Help would be much appreciated!
