Any chance to you can the thread up today? Advice against hotmail for now as well.
Also, the DBTech - vBMail via ACP seems to be broken. Few users (including me) have set Bounce Flag to Yes, which prevents users from receiving any mail from mailing lists. No idea why mine is set to Bounce Flag. My email is valid.
I was advised to manually change that to No last week to see if it fixes the email confirmation issue (whether it's related or not, I don't know), which I did for myself, but after re-checking today, I found that it automatically sets it back to Yes. Notified techies about it.
