Mail sent to r...@foo.com reflects immediately in the user's webmail, Outlook, couple of other mail clients, but NOT his BB. It may take anything from 15 seconds (acceptable) up to an hour (definitely not acceptable) to reach his BB.
From one of your previous emails related to the scenario you mentioned above, I infer that you're using Courier. Also, you are using IMAP instead of POP3 since your r...@bar.com receives mail instantly.
There's an IMAP feature called IDLE which enables detection of incoming emails. So, as soon as an email comes, the client is intimated instantly - provided the client understands IMAP IDLE. However, from my experience, Courier's implementation of IMAP IDLE is not optimum. I've seen that the client is IMAP IDLE capable, and is connected but Courier doesn't intimate the client when a new email comes.
Dovecot on the other hand implements it rather well. There could be a possibility that the blackberry's imap client with the service provider which is pulling mail from your server has established a connection but is not intimated by Courier that new mail has arrived. Either a flawed IMAP client or it's Courier.
There's an ENHANCED IDLE mode too, but I am not sure if that'll make any difference. Moving to dovecot solved a lot of 'push' email concerns for me though.
