Looking for advanced experienced Postfix administrator in configuring our Postfix SMTP server for email marketing newsletters and configure the best delivery options to avoid getting blacklisted with major mail servers (yahoo, gmail, hotmail etc).
We have a Ubuntu 10 LTS server used to send a large list of email newsletters.
We want to install 3 instances of Postfix to send email using 3 different IP addresses configured in the server, to be used for 3 different domain names,
Emails sent by each domain name must be identified by its own IP address. 3 IP addresses for 3 domain names.
So the job includes configuring POSTFIX to accept email delivery from other locations (relay). Enabling a list of permitted IP addresses.
Apply the best configuration options for email delivery of 200.000 emails per day per IP, we will probably be using Interspire Email Marketer on the same server or on another server and send through this server.
Check and adjust: configuration of mailserver, SPF, domain keys DKIM for the 3 domains hosted on the server.
Since we host the DNS zones in another server, you must provide us with the information to do what is needed regarding this.
Enable the 3 postfix installations to be managed through webmin.
The server is only used to send email for these domain names, the email accounts for these domains are already configured on google apps
Important: they must be 3 independent postfix installations
