move postfix mails from server to another postfix server
i've a big issue with postfix, i've to move a lot of mails (approx.23000) from one postfix server to the new one.
it does'nt where the mails are located in the future, that means it is no problem for the user (but for me) if they find there old mails in a new additional folder...
can someone give me a hint or maybe a little bit more information how to handle this issue??
thank you all!!
