Hello,
I will configure SMTP server with all mailing authentications like SPF, DKIM, DMARC, RDNS, IP rotation etc.
I have more than 5 years of experience in email marketing, bulk mailing, installing and configure Mailing applications like Mailwizz, Mautic, Sendgrid, SMTP's PowerMTA, AWS SES etc.
I would like to have a discussion with you to explain things in better way.
Thank You
