Forwarding old emails

Question

I'm trying to forward a series of old emails from one email address to another, both are Microsoft email accounts. The thing is that i don't what to simply forward them using the web interface, that creates a "wrapper email" that contains the original message.

From what I understand of the email protocol there is a chain of "Received:" headers that contains the servers where the email passed by. I just want to forward them to the new email as if they were forwarded if the fist place if I had configured my inbox to do so (maintaining all the "attributes" including from, to, subject etc).

From what I searched, I think that this can be done by a program that connects to the POP and SMTP server of the old inbox and forwards the emails to the new inbox.

I tried using the the gnu tool movemail but there is a problem when specifying the original pop server, the syntax is pop://user:pass@popserver:port. When using an Microsoft email (the email address is the username): pop://[e-mail]:[e-mail] the program fails because there is two @ signs on the parameter (using %40 does no help).

Then I tried fetchmail I could not get it to work because it does not support SSL on the SMTP connection only on the POP, the Microsoft POP and SMTP servers both require a secure connection.

Is there any other way of doing this? Using some other tool for lixux or windows?

Thanks for your help

Answer 1

The way I usually handle these kinds of things is to set one account as POP3 and the other account as IMAP with the mail client application of my choice (ie Thunderbird or Outlook).

Source account - POP3 Destination account - IMAP

I'll download all of the mail from the POP3 account and then copy it over to the IMAP account. The IMAP account will synchonize with the mail server, uploading my other account's emails to my new main account.
