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,
