| | how does a blackberry communicate with BES
Please Login to Remove!
I am a network analyst and we are currently looking into buying blackberrys and installing them. We have a few hurdles to over come that I have found work arounds for (i.e. our main email is MDAEMON so we are going to use sbs exchaneg on a small domain and relay email between the two). What I want to know is, how do blackberry devices communicate with the Blackberry enterprise server? do they use DNS or do they use ip addresses?
