I pay a developer for private mass mail creation on Linod

I'm looking for someone who could install a private email server on my Linode, with SMTP for mass mailing service for our clients, with all handling (bounces, spam, autoresponder, dkim, aso).

The most easy to use, because I'm not a boss in codes.

Volume mini : 100 000 emails/day to 500 000/day

Payment ok… of course.

NOT ON AMAZON SES !!!
