I have a very strange problem - recently, in the last week, many of my mails are not getting through to users.
I am getting errors like this (this is a valid hotmail address as it is mine!). PowerDNN recently changed all my email passwords (due to a vulnerability), but the only place where a SMTP mail password is stored is under the Host SMTP settings and I have changed this to match the new password for this user (you can see my settings here: http://screencast.com/t/l8pt1xejAuMw )
I'm getting users complaining of never receiving emails - and I am out of ideas - any suggestions please?
