Our old IT guy left and upon exiting he told us the following in an email:
You currently use Luxsci/Mcafee which is end-of life in Jan of 2017. You will need to get another cloud email filtering provider before then to avoid disruption in your mail.
On your end, it should just be a matter of changing mx records.
I'm not a big email guy, so could someone recommend a cloud email filtering provider and give me a quick run down on changing the mx record? I've messed with mx records but it's been a very long time. We run exchange 2010. Thanks in advance.
