Notification to members that emails to any of the following domains are being bounced - Yet again!
This is affecting the registration confirmation for new forum members and notifications for subscribed topics & personal messages.
Yet again we appear to be an innocent victim of Microsoft's 'Smart Filter' despite following all their rules.
The domain is clean and definitely not on any blacklists - See MX Toolbox Blacklist check.
This is the third time this has happened. Both times in the past Microsoft admitted it was an error on their part and we should not have been blacklisted and agreed to mitigate the domain.
We are not the only reputable site this is happening to and its becoming an irksome routine for many other websites too.
TBF I do not have time today to spend the hours that it takes chasing MS and am so fed up of their ridiculously broken system that I am considering blacklisting all their email addresses if I can find a way which doesn't affect existing members accounts.
