One of the accounts in our organization has been blocked and the reason is simply mentioned as "unknown" in the Mail&Docs control panel. 

Could you please unblock it since we need to carry on day to day business communications through it. Also let me know why it was blocked. Don't think we exceeded 10 per day bounce or 250 mails a day outgoing limit. 

Email ID is: info(at)karpassa(dot)com

I have also attached screenshot. Goes without saying how random and frustrating this is. 

Thanks.
