I don't know if I am posting this in the right place.

I have notifications set to send me an email. However, I am no longer receiving emails from this support forums. I don't know if the problems is at my end or at your end. I've already whitelisted @invisionpower.com at our anti-spam software, at no avail.

Our email service logs show your server is rejecting our emails to you. I am afraid it doesn't tell me more details.

I see you use Mandrill... Our server was rejecting Mandrill-sent emails due to the high volume of spam coming from Mandrill... Removed... Thanks!
