I've a client who has moved from an on premises Exchange 2010 server to Microsoft Hosted Exchange (Office 365) He was using GFI's Mail Essentials when he had his own mail server which worked very well. However GFI's online Mail Essentials is very lacking compared to the in house version.
I'm looking for suggestions to an alternate solution. Actually I'd be happy if I could configure the hosted Exchange to use RBL's, etc.
Thanks in advance!
