Hi,

In the context of migration from an MSExchaneg to Postfix ,

I 'm tring to reproduce a functionality:
Until we have migrated all the 300 mailboxes, I want to put my new Postfix as a front end.
It would firstly receive the SMTP stream: if the recipient mailbox is localy existing on it then deliver localy (maildir format) and if the mailbox is not yet exising (user not migret) it would then transferred the mail to the old server.

I'm using Dovecot as LDA (and POP3/IMAP too)





If anyone know how to produce this...

any ahelp appreciate.



Thanks in advance.





Regards,

Hi all,

here is my first post and I'm here to learn more of postfix, I'm not an expert,
so I will be happy to be corrected if I say something wrong.

actually I noticed that this could be done with transport

mydomain.com smtp:[ip_address_or_hostname_of_exchange]

while I was testing this configuration I noticed that only non-existant
mailboxes were forwarded to the other smtp, while mailboxes that actually
existed in my user table were delivered locally.

Regards,
Stefano L.

Hi,

You can use the /etc/postfix/virtual file to have a list of local
email addresses and their corresponding alternative address.

I'm new to postfix myself, but say you have 2 machines both configured
to deliver mail for a single address guy(a)mail.com for example

Postfix delivers mail to the local system for all it's users, but for
anyone that has yet to migrate, in the virtual table, you put the
email address and the forwarding address to the servers with the user
like

guy(a)mail.com Guy%mail.com(a)10.0.0.1


I had to migrate about 100 people, I just kept it all by hand and used
the virtual file to manage where email went.
