all my accounts that i have forwarded down to my bell.blackberry.net (email account side, ie. filter: send a copy of all mail to
) is real time, but anything I added for the BIS to extract mail from, ie. sympatico.ca, joescully.com all were polled in the 0 - 15 minute window.
from what I've read, only IMAP accounts are real time...but I don't know for sure.
