Job ID: 33104081

Budget: €60 – €80 EUR

Hi all,
We already finished iRedMail installation on CentOS 8,2. We want our iRedMail accounts could download email from some user in our internet domain to our local domain ex: user1$internetdomain.com will be download to user1$localdomain.local without migrating mail server (we have try using fetchmail and it success).

We need to sending email out from user1$localdomain.local to all internet domain using postfix smtp authentication/MTA relay (mail.internetdomain.com:587).

Please note that:
1)The local domain located on a local server, so we cannot provide you access to the Server.
2)The local domain is not public known.
