    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.

    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:

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

    poll 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:


    set daemon 120
    set syslog
    set postmaster "[email protected]"
    set no bouncemail

    timeout 300
    antispam -1
    batchlimit 100

    poll protocol POP3 no dns localdomains username "test" password "test" to * here

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

    and it doesn't fetch e-mails :(

    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.
