Corporate Mail Dedicated Managed Server
Effective management and control of the information flowing through corporate email systems is imperative, in some cases mandatory. Organizations have seen their corporate email system become a de facto repository and distribution mechanism for the vast majority of their data and corporate knowledge. What's more, vast amounts of personal, non-business related, and other types of possibly inappropriate information is flowing through (and stored within!) corporate email networks. Once inside the email environment it is extremely difficult to protect and control the information.
The Spam assault on the inbox will increase to 82% of all Internet email traffic by 2011 according to the Radicati Group. To combat this trend, we use the Anti-Spam Live Service (Live Identification and Verification Engine) Service to bring CertHost Managed Server Antispam identification to near perfect accuracy as spam far surpasses unmanageable levels.
It is estimated that spam accounts for roughly two thirds of all corporate email traffic adding cost, complexity in management, increasing security risks and introducing one of the most well hidden Trojan horses to organizations today lack of productivity.
We will supply it the best Corporate Mail service that will solve all most common company problems about email Messages.

Others Specifications:
Data Encryption
Login credentials are by default protected with passwords using RSA public-key asymmetric cryptographic methods, also implemented by SSL traffic encryption to prevent eavesdropping and data tampering. Either the supplied, custom or trusted CA acknowledged server certificate can be used.
Messages can be signed using public-private key combination just like in PGP, but server-side without the need for extra software in email client.
- SSL/TLS 128-bit encryption for all services
- Secure SMTP Server
- Secure POP Server
- Secure IMAP Server
- Secure Web Mail Server
- Digital Certificates Creation and Management
- Secured Destinations (force SSL)
- Authentication: CRAM/Digest MD5, login, plain, POP before SMTP
- Server-side message encryption using S/MIME
- TCP/IP tunneling front-end (VPN like operation)
Password Catching Protection
Apart from many options to enforce password policies, passwords can be safe from the beginning, using built-in password generator, and validated against a required level of password strength to prevent dictionary attacks.
- Extensive password, expiration and login policies
- License generator and password validation
- Account login IP restriction
- Change passwords over POP3 protocol
- Service authentication- support for superuser login syntax
Denial of Service Protection
Advanced rate control allows to set limits for each service in terms of outgoing and incoming connections, data transferred over a defined period or simultaneously established sessions. Even local senders can be checked for viruses and spam and their daily email usage restricted to prevent abuse through leaked or weak passwords.
- Bandwidth throttling per service
- Data and connection rate control
- Service usage policies
- Traffic monitoring with alerts
- Command monitoring
- Service usage restrictions
- Allow/ban host rules with host patterns
- SMTP- Web/Control service cross-monitoring watchdog
Anti-Bombing
Sending bulk amounts of mail can be effectively prevented by extensive session and protocol control policies. Some of the common SMTP protocol weaknesses used to collect email addresses can be disabled, along with other commands if not in use.
- Protocol policies and session control
- Session inactivity timeout, Protocol response delay, Max bad commands, Max outstanding connection requests
- Perform a delay before processing an incoming SMTP connection
- Disable telnet access
- SMTP policies- disable EHLO, AUTH, EXPN, VRFY commands
Anti-Spoofing
Forged message headers are common especially in phishing attacks. DNS checks are performed to ensure credibility of the sending email server and subsequently of email it sends. Further level of protection is the support for DomainKey Identified Mail and related security standards originally introduced by Yahoo!.
- DNS MX and A record authorization
- rDNS validation
- Security standard SPF with SRS support
- DKIM, domain literals
Anti-Relaying
Closed relay is crucial in preventing abuse of the server for sending spam and being blacklisted by other servers in turn. On the other hand, there are options to reject connections from servers which are open relays.
- Closed relay except for Trusted IPs
- Domain IP shielding, IP Binding
- Non-authorized domain rejection
- Hop count and number of recipients restrictions
- DNSBL query
- HELO-EHLO filter
Intrusion Prevention
This system is monitoring attempts to deliver to unknown users, to abuse SMTP commands, to send spam or to relay without authentication and when a certain treshold is reached, automatically closing further sessions for a period of time or permanently blocking connections from such IP addresses.
- Cross-session and cross-protocol monitoring
- Management of intruders' IPs
- Reasons for blocked hosts displayed
- Helpful against spam and DoS attacks
Backup and Recovery
Backup your server settings and accounts regularly with an automatic schedule, or manually with a single click of a button. Restoring your system is as quick and simple as the backup. All backups and archives deploy ZIP compression algorithm, allowing to use popular compression utilities to browse the files as easily as exploring a directory structure, while minimizing occupied space.
- One-click manual Backup and Restore
- Scheduled Backup
- Incremental Backup
- Log Backup to track down server activity
- Backup all or any subset of data, settings, accounts
- Possibility to include external directories
- Remote fileserver connectivity
- Backup GroupWare data by mirroring the DB, using backup tools or to a file
- User can backup Outlook GroupWare data to quickly restore PSTs
Archiving
All communication can be archived for administrative and legal purposes. To comply with regulations such as the Sarbanes-Oxley Act ( SARBOX ), there's server-side message archive with rotation and backup. Afterwards the archives can be automatically deleted after a specified number of days, or kept indefinitely. Messages are saved as files in a tree folder structure, which makes the restore just a matter of extracting content of archives to a selected IMAP folder and they are immediately available for audit.
- Archivation utility with archive rotation, backup, scheduling
- Archive all, only sent, only recieved messages
- Forward or save incoming/outgoing copies to e-mail for revision
- Password protected backup of deleted messages
Filtering
Internal communication policies can be easily enforced by usage limits and advanced filtering and content scanning methods, eliminating undesirable content. Actions taken upon discovering infringement include deleting or forwarding the message, notifying administrator, running external processes or banning the sender.
- Server/domain/group/user level quota and limits
- Message processing Rules
- Content Indexing- block messages based on number of duplicates received
- Extensive Content Filters with RegEx support
- Flexible, customizable filters scan message content for keywords and phrases
- Execute application action
- SQL statement action allows to use own DB, make queries, insert statements
- External filters (command, script, function)

To significantly reduce false positive identification without decreasing Anti-Spam efficiency, email from unknown senders that the our system cannot clearly identify as Spam can be quarantined for manual review and processing by end users. End users have full access to their own quarantine folder, allowing them to inspect and whitelist any messages incorrectly tagged as spam, thus ensuring that sender's email will bypass any Spam analysis in the future and be delivered directly to the recipient's inbox. Semi-automatic processing is also possible via the use of Challenge Response - senders of quarantined messages will receive an email notification that their email has been delivered to the recipient's inbox and allowing them to manually authorize themselves by comleting a short challenge / response confirmation.
The quarantine service provides:
- Daily quarantine reports by email
- Details shown include Subject, From, Date/Time
- Works with any HTML capable email client
- Not message but sender based
- Actions/Voting links to Authorize sender, Delete or one-time Deliver messages
- Users can manage and inspect Quarantine from WebMail

- Messages left in quarantine are deleted on schedule
- Authorized senders won't be tagged/challenged ever again
Automatic Whitelisting
Automated Whitelisting is a powerful tool that ensures messages from legitimate business contacts that you communicate with will never be tagged as spam. The recipient of any email manually sent by a user on the Dedicated Managed Mail Server will automaticaly be added to the whitelist thus eliminating the fear of losing critical messages from those you communicate with.
