[maildropl] forwarding mail via maildrop to same account on other servers?

[Thomas S. <tho...@my...>]

Hey folks,

for moving mail-services to another server I usually used the
transport-maps to forward single accounts or domains to another
server while dns has to keep up with the changes.
With using maildrop as virtual-delivery agent this doesn't seem to work.
Therefore I'm wondering if there is any way to forward mails to the same
email-addresse but on another server?

With transport maps it was something like:
na...@do...   :[new.servername.com]

Any ideas?

Thanks in advance,

thomas
