MailEnable Enterprise includes all the features of MailEnable Professional and is designed for organizations, hosting companies or ISP's dealing with high volumes of mail, requiring greater control and flexibility over mail services.
MailEnable Enterprise adds highly functional features such as Collaboration, Outlook synchronization, remote administration, more advanced webmail and web administration, and database connectivity - giving you the power and control required for large-scale operations.
SyncML allows the synchronization of MailEnable calendar, tasks and contacts with Mobile devices (Phones, PDAs and Outlook). The SyncML server detects changes made to your contacts, calendar or tasks, and prepares the updates for transmission to SyncML clients (Mobile devices). Likewise, changes made on your SyncML capable Mobile devices are transacted to the server.
MailEnable's Domain Keys (DKIM) implementation provides inbound validation and outbound signing of messages. The extensive filtering provided by MailEnable allows you to discriminate messages according to their domain key validation. Administrators can either use inbuilt simple criteria or tailor complex scripts according to filtering requirements.
MailEnable Enterprise provides an SMS connector which allows you to send SMS messages from MailEnable. Administrators are able to define SMTP addresses that are mapped to mobile phones. Any messages received to that address are processed by the connector and sent as an SMS to the corresponding mobile phone.
MailEnable's SMTP service has been updated to provide outbound TLS/SSL support, allowing the secure/encrypted transmission of messages to remote SMTP servers.
MailEnable Enterprise includes end-user activity reporting. This allows mail users to view the last 5 days of significant activity performed against their mailbox. For example, a user can see whether messages were deleted from their mailbox or even whether an e-mail message to their account has been greylisted/suspended for later delivery. 
Authentication methods such as APOP and SMTP Authentication, CRAM MD5, Secure Password Authentication (NTLM support) and advanced relay settings control user access to your mail server.
Secure Sockets Layer (SSL) support for SMTP, POP and IMAP protocols allows mail clients to connect to the server securely by ensuring that mail communications between the mail client and MailEnable are encrypted.
A new reporting module provides detailed statistics on all mail services (POP, SMTP, IMAP, HTTPMAIL) and the MTA. Over 80 different reports can be generated and ranked by user, post office or for the whole system. Information can be tabulated on data sent, data received, data total, messages sent, messages received, user log-ins and client connections.
MailEnable now includes a monitoring agent that checks system health and can notify an email address of any problems that are detected, such as a large amount of email going through the system, or service failure.
MailEnable now provides support for a third SMS gateway service provider, Intelli Messaging. Now there is more choice with provider, and with some simple entry of your account details within MailEnable you will be able to do email-to-SMS in no time. With MailEnable you will be able to monitor your webmail even at distance.
