Hello I'm in trouble with an old Qmail server that runs on an also old server.
The problem is I cannot modify the existing configuration of this machine because of inhouse developped applications that use qmail. Qmail ( which i know very few ) seem a bit autistic when talking to non FQDN distants servers or with MX misconfigured. my idea is to add a postfix instance on this machine which will send emails to the Internet. In my plan Qmail will inject all outgoing SMTP traffic into Postfix instance that will send it outside . it that config I could tweak postfix as I want to manage outgoing emails. The server is mainly used to send daily newsletters Anyone did this ? Is it possible ? Thank you
