I've searched and read fragmented information on these protocols, but wanted to get someone's opinion. I have an SBS 2003 server running exchange, serving mail to about 15 users. Currently most of the users have hosted mailboxes that are being retrieved by the SBS POP3 Connector. I'm not thrilled at the prospect of 15 minute polling because 5 of us use Blackberries and our BES has to wait on Exchange to poll the POP boxes before pushing mail out to the handhelds. I'm also leary of creating an MX entry to just point to my server in case of down time. So, that being said...
Which setup would you recommend for my situation?
A)Third Party POP3 Connector running at a 30-60 sec polling interval?
I'm open to any suggestions.
