Hi all,
I want to setup a new distribution list in our exim/dovecot setup On
Solaris 10 servers
I have read the documentations but I haven't clear where i have to setup it.

I have created the team.txt file with all the email addresses for the list.
team.txt which contais:
emai1@???
email2@???
.

.
emailn@???

Now I want to setup team@??? to distribute email to this address to
all components of the list.
But I don't know how to setup.
Thanks a lot in advance help
