Currently, we have a few registered URL's and send automated messages from our normal servers (using GMAIL). However, we plan on greatly increasing our mail volume as client base grows. Our biggest concerns are making sure we don't get marked as spam automatically.
I) We are looking for step-by-step instructions for setting up and managing one or more email servers
a) we will have dedicated domains
b) we will be can-spam compliant and all other relevant laws
II) primary focus should be on
a) best practices for sending mail
b) being kept off of spam marks
c) step by step instructions of handling different spam marking scenarios in
III) other areas of interest
a) useful software
b) other best practices to follow
Will start with a few minutes of us explaining the issues and will end with a step-by-step document including examples of how to handle that any linux/ubuntu sysadmin could follow.
The project does NOT include setting up the system.
