help : migration from MS Exchnage to Postfix

[asmaa]

Hello,

I have a problem and I need your help.

We are using MS Echange for our mails and now I want to migrate to postfix but I want to do it step by step because I don't have a big knowledge in Linux.

What I need to do is to have the two servers (MS Echange and PostFix) at the same time and for the same domain.

So how can the users that have a count on the postfix server receive mails from outside. These users don't have a count on the MS Exchange.

Thanks for your help.

asmaa,

Postfix is a Mail Transfer Agent and doesn't hold user accounts, it simply moves mail.

Can you be more specific about what your trying to achieve?

i did the same thing as you for our company and so far it is working out great!! we will never use MS Exchange again.J

You want postfix as the mail server. It transfers mail to and from your domain and outside domains. I believe it does hold all mail going to the local domain that it servers, (i might be wrong) from which your local users will receive mail.

You will need qpopper as the agent which users will use to log into to the postfix server to receive their mail.

You will probably also need pop-before-smtp if any of the mail users are going to be traveling and need to access mail from outside the LAN.

You can install all three on the same server. Advice: use the latest Red Hat (9.0), all the latest rpm’s from the respective sites and a lot of patience. You can use 7.3 but you will have to upgrade much of the server software (openssl , perl, etc). To answer your question: set up postfix and have both run at the same time. Once it is stable and ready to go, transfer the accounts little by little and let the users know before hand before you do. I don’t think it is possible to transfer mailboxes and users to and from the two different operating systems.

I use postfix for mail transfer for a small business. Runs on headless PII 200 server with 132Mb RAM and RH 7.3. (Does other jobs too like Samba. No plans to upgrade. If it aint broken, then don't fix it.)
I use fetchmail to pull the emails from our ISP. Postfix handles both inbound and outbound delivery of email.
Postfix just keeps working so well I forget that its there.
Oh, and the weekly email of warnings and stats to the admin user keeps me informed that its all ticking along nicely.
