I am preparing to convert my main client's postfix_courier-imap setup to 
dovecot 2.1, which currently just uses the postfix virtual delivery agent...

Does anyone know if the use of LMTP (or even the dovecot LDA) still 
loses the x-original-to header that the postfix vda adds and that I rely 
heavily on (since I use a lot of aliases), and if it does, is there any 
solution to get the original recipient added back in before final delivery?

Everything I'm reading says that LMTP is better, but I really do need 
this header (or one like it) to be there so I know who the original 
recipient was (for filtering and other purposes).

Thanks,
