Hi..
I can make this work because I am already working as a system administrator (email delivery specialist). As you have mentioned in the proposal that you need to resolve your dns issue. I can do this job.
Allow me to introduce myself as a systems administrator with over four years of practical expertise. My skills cover a wide range of areas including web server administration,(WHM/cPanel, CWP, Vestacp etc ), DNS management, mail server configuration (Postfix, Exim, Office 365, G Suite), web server setup, WordPress, MySQL, Cloudflare, DNS record management, and efficient management. Email Services, Git/Github. In addition, I have strong experience in setting up SMTP, IMAP, Outlook configurations, and integration with various third-party SMTP services.
I hope we can communicate more on the project but before start, I can do this task on team viewer.
Best regards
