Mail-in-a-Box
Mail-in-a-Box lets you become your own mail service provider in a few easy steps. It’s sort of like making your own gmail, but one you control from top to bottom.
Technically, Mail-in-a-Box turns a fresh cloud computer into a working mail server. But you don’t need to be a technology expert to set it up.
Each Mail-in-a-Box provides webmail and an IMAP/SMTP server for use with mobile devices and desktop mail software. It also includes contacts and calendar synchronization.
The box also includes other standard mail functionality like spam protection (spam filtering and greylisting), mail filter rules, email client autoconfiguration, and automated backups to Amazon S3 and other services.
The box also includes automatic DNS configuration when you let it become your nameserver so that it can set important DNS records for mail deliverability and security including SPF, DKIM, DMARC, and MTA-STS. When enabled, DNSSEC (with DANE TLSA) provides a higher level of protection.

"Very good mail server with GUI" Posted 2025-01-05
Pros: GUI configuration is very important.
This simplifies a lot of things. It has an installer and well documented.Cons: Windows only.
hMailServer is no longer being actively developed. The latest major version was released several years ago and since then only critical updates have been released. hMailServer relies on algorithms which are considered insecure by modern standards, such as SHA1.Overall: It works well, a good solution for a small business to install on a Windows server. I used if for a self hosting.
