With Gmail and Yahoo! accounts the e-mail will come through instantly almost. With other POP3 and IMAP accounts, or Exchange accounts, the mailbox is polled every 15-20 minutes.
Blackberry may have different polling rules for IMAP accounts. Just added IMAP email address to my blackberry today and can swear I am getting emails from it much faster.
My POP3 email is delayed by 15 minutes, just like you say.
