Hello
I am a system and network administrator, with more than 10 years of experience.
During that period I have installed, administrate and maintain a large number of various servers, such as Web Server (Apache, IIS), Mail Server (Postfix, Exim, MS Exchange),
DNS Server (BIND, Unbound, MS DNS), etc., based on, FreeBSD, CentOS, RHEL, etc. And of course, I have a lot of experience working with MS Servers and other MS products.
As well as I have some experience in the database design, development, and maintenance.
As for the project, you should know that Google won't allow you to use email service directly from GCP Instance. Instead, you will have to use third-party services like Mailgun or Mailgrid.
Thank you in advance. Looking forward to hearing from you soon.
Sincerely
Eduard
