I don't know whether this is asked already or not but I could not find the solution.
I want all my existing mails to be forwarded to another mail (yahoo/gmail) account. There are some thousands of mails. What is the best way to forward/export all preferably in an organised way (keeping the inbox, sent mails etc. and the labels).
I found some restrictions like if a user sends to more than some hundred recipients, or if most (not sure how much) out of the recipients are invalid/non-existent mail ids then gmail temporarily blocks the mail id without any notice (something similar). I don't want this to happen.
