Introduction to H-Sphere Mail

H-Sphere mail system consists of the following blocks:

1. H-Sphere Mail Service: includes Qmail SMTP server with a number of antispam/antivirus and other extensions, vpopmail POP3 server, and a number of other applications.
2. H-Sphere Webmails: two analogous webmail applications, SqWebMail and IMP to manage mail through web interface. System administrators can choose which of them will be offered to hosting customers. Apache used by these packages is the same as on the H-Sphere web servers.
3. H-Sphere IMAP Server: Courier-IMAP server package. Since H-Sphere 2.4 Patch 4, it is included into H-Sphere mail system by default.
4. H-Sphere Daemontools (added in H-Sphere 2.4.2): a collection of tools for managing UNIX services (such as ClamAV) adapted for H-Sphere.

In the future, we are planning to implement separate package for DCC Server.
