how to migrate mail messagges from ms. exchange to postfix?

[koi]

Hi, I have to migrate e-mail messagges from a ms exchange server to a postfix server.

I have found nothing, the only thing I have in mind is to use fetchmail on the postfix server to get the e-mail messagges from the ms exchange server.

Is this correct?

Are there other methods, like "copy" e-mail from one machine to the other?

Which format are the exchange e-mail stored in?

Thanks in advance.

I have no idea what format Exchange uses to store emails, so I think fetchmail or getmail would be the best options.

Thanks. Is all ok, but I am in the need of retrieving e-mail from a mail server (to the new mail-server) inside the same lan.
If I put in fetchmail something like:

(192.168.10.254 is the old mail server from which I have to fetch e-mails)

poll 192.168.10.254 protocol imap user....

I always get: fetchmail: no mailservers have been specified.

Does fetchmail only accepts fqdn after the "poll" ?

Thanks in advance.

No, IP addresses are ok. What's in your /etc/fetchmailrc?
Any errors in the mail log?

No errors, I always get: fetchmail: no mailservers have been specified if I put a class c address. :mad:

/etc/fetchmailrc

set daemon 120
set syslog
set postmaster "postamaster@xxx.com"
set no bouncemail

defaults:
timeout 300
antispam -1
batchlimit 100

poll 192.168.10.254 protocol POP3 no dns localdomains example.com username "test" password "test" to * here

NEWS: now it seems to accept class c addresses, but I get:
Server CommonName mismatch: mailserver.example.com != 192.168.10.254
Server certificate verification error: self signed certificate

and it doesn't fetch e-mails :(

Can you specify mailserver.example.com in fetchmailrc instead of 192.168.10.254?

Fetchmail can only be used for mail in transit, you need to use imapsync to do the migration it will preserve all the message flags.
