Thank you for this opportunity.
Just to be certain, we are on the same page, i understand that you require a mail server to be installed locally on a server (mac mini) within your premises.
You do not want a cloud hosted solution but a system you have total control of.
I have over 10 years working with diverse email platforms.
I have worked with both paid and open source platforms with nothing but the best of results.
If my proposal is accepted we will have a requirements elicitation session just to ensure alignment in terms of expectations and select the best platform based on our discussion.
The project will follow the folloing flow:
System Design
Purchasing (if required)
Preliminary installation
Complete installation,
Integration,
Testing
Acceptance
Close.
If the requirements are not too much, i may conclude the project before the stipulated 4 weeks.
Please contact me at if you would like to take this further.
