Hi, we could help you host your “Email Service provider” service on our cloud platform. We could provide you following features:
1. Multiple Users per email domain, for each package, without any extra cost. Only limitation is the hardware (cpu, ram, ssd) allocated to the package you buy from us. Details explained below.
2. Multiple Domains (each for a different customer), without any extra cost. Details explained below.
3. Webmail, which also provides forwarding and an out of office reply option. You may also use your own Webmail application.
4. Authenticated IMAP/SMTP for use with any email client, on mobile devices and desktop. It also includes contacts and calendar synchronization.
5. Easy client configuration - autoconfig support for Thunderbird and autodiscover support for Outlook.
6. Optional two factor authentication
7. Individual email whitelists and blacklists and spam thresholds, configurable by users
Explanation for 1. & 2. -> You can have as many customer domains, each with as many users. Limitation is the infrastructure you are allocated as part of your package. Higher packages have better infrastructure configuration to handle higher loads. You may start with a base package, and as you keep adding users / customers, you may gradually upgrade to higher packages.
We plan to release a Beta version of our Email Service, in the 1st week of January, 2019.
There is not enough space here for me to describe our package details. We can discuss more on chat.
Thanks
