OK, I have now gone through the WordPress Forum and GoDaddy Support Forum
and have done the following:
1) Installed the *WP-Mail-SMTP *as per the WordPress forum;
2) set the SMPT host to relay-hosting.secureserver.net as per the GoDaddy
support forum on the Subscribe2 plugin and this very problem
Then tried emailing from the blog forthefirstime.ca and this is what we got
back:
*
Message failed! Check your settings and check with your hosting provider
SMTP Error: The following SMTP Error: Data not
accepted. (followed by the
full list of subscriber email addresses…)
Of course, GoDaddy just keeps telling me that they can see emails going through.
What’s my next step?
