Topic: Enable relay from send mail trough iredmail (Postfix)

Hi All,
1st i want to say IREDMAIL is amazing project and i love using it.

my problem is as followed:

I have TWO Sites, Site 1 is a scalix server with sendmail and the other is IREDMAIL with postfix (no ldap installed).
I want to Scalix sendmail to use IREDMAIL as a SMARTHOST.

i have configure sendmail SMARTHOST Auth  BUT when ever i'm trying to send an email from Site 1 (Scalix) i see at the IREDMAIL postfix logs that "Sender address rejected: not owned by user USER1@domain.net" and IF i'm sending an email from USER1 i'm able to send it.

what can i do to enable a realy option with IREDMAIL

please help,
i'm stuck for Two days with this issue.

Add server IP address of Scalix in mynetworks (iredmail, /etc/postfix/main.cf).


Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
