Hello! I am Olha, a professional Web Developer with 5 years of experience in website building, offering a complete cycle of services from UX/UI Design to Development, SEO, and Marketing. I understand that you are looking for a way to enable Thunderbird on your Mac to send emails from your server but the error message prevents this from happening. With my expertise in web development and system administration, I can help solve this problem.
I have extensive knowledge of online security and reliable software such as Let's Encrypt SSL that auto renews every 3 months. Additionally, my server runs Virtualmin/Webmin with Ubuntu Linux 20.04 which provides ample resources such as 6 cores, 16 GB RAM, 100 GB (100% NVMe) storage for your needs. If you choose me for this job please feel free to contact me directly for further discussion or any other questions you may have. Thank you for considering me for this project!
