Saving to both RT and mailbox

is it possible to have the emails be processed by RT-mailgate and at the same time be saved into a corresponding mailbox?

i have RT installed both on remote server A and local server B. server A will pass the emails to rt-mailgate
and at the same time save it to a mailbox. server B will retrieve the mails (that are saved into the mailbox in server A)
thru POP and forward it to rt-mailgate of server B.
