Attachments replaced with WebDAV URL, file saved to user's mailbox files folder. Gives user the power to delete, swap and update attachments after the message has been sent. Customization includes account, folder name, expiration, custom header/footer, anonymous or authenticated mode. Variables for attachment file size, expiration time, textual expiration date, message index, download URL. Supports Unicode filenames. Supported by WebClient and Content Filters.
Mail Archive can now be categorized by user account, divided into subfolders by timeline, and depending on administrator settings, it can contain all e-mail history of received and sent messages from all folders, including SMS. Mail Archive is integrated with IMAP and accessible in read-only mode from any email client or WebClient, and each user can have it subscribed by default. Taking advantage of Permissions and Public folders, administrator can create an Archivist user role, granting a person access to the whole server archive, archive folder of selected domains, groups or users for e-discovery. Supports IMAP flags. 4 new archive modes.
Account sharing, email folder sharing, extensive bit rights, inherited permissions. IMAP ACL RFC 4314 compliant, obsolete rights of RFC 2086 supported exactly as in RFC.
LB environment is automatically detected if ServerID is used.
Master host option, slave server requests processed by master, requires proper settings of Master, Master Host and Slave Hosts.
GroupWare attachments (to contacts, events), user's File folder, extracted SmartAttach attachments are stored in mailbox/~gw/attachments/ to enforce mailbox/domain quota and archivation along with emails. Original storage calendar/attachments/ is automatically converted when the mailbox attachments storage accessed for the first time.
Protects the server from being flooded by bouncebacks with forged From. If Use SRS NDR (Non-Deliverable Reports) Validation option is on and a bounce back is received without valid hash or SRS message, it will be rejected.
Splits a domain into logical parts with distinct settings and users. A set of domains is grouped into a cluster with one domain defined as a master domain. The master domain then serves as a "dynamic alias" for all the other domains. Makes sure it is not possible to create the same account within the cluster.
The server is still 32-bit application but can take advantage of the whole 4 GB of user addressing space on 64-bit systems.

DB and FS Health Monitoring
Checks DB health in multiple connections and availability of config, mail and temp paths every minute and if down, SMTP, POP3 and IMAP socket servers are paused and no more incoming connections are processed (email client reports a server error instead of failed user authentication).
Intrusion prevention – Failed Logins
New option to Block IP address that exceeded number of failed login attempts (if Login policy is enabled).
LDAP/Active Directory Synchronization- SASL
Plain text authentication for LDAP/AD users updates the local password so SASL authentication works all the time, auto updates after WebMail login (RSA protected plain text authentication to IMAP).
LDAP/Active Directory Synchronization- FROM
New internal XML options (LDAPUSERFROMDN, USERNAMEFROMCN) for user's mailbox and LDAP authentication.
LDAP/Active Directory Synchronization- Filters
Introduces custom filters what account/groups to synchronize (<objectclass>[":"<filter>]). SIZELIMIT_EXCEEDED error logged if query size limit is exceeded.
LDAP/Active Directory Synchronization- Local Groups
Synchronization always preserves manually created users and groups, even if missing on directory server, using the Personalized bit flag 0x10.
Remote Client Deployment
From server directory /install available remotely at http://server/install/ (option in Setup). setupinstall.dat package added, contains client applications, installed to /install directory.
Mailing Lists – Message ID
Mailing Lists display original message ID in the client sessions logs.
Mailing Lists – BATV SRV
Mailing list authentication works correctly with BATV SRV encoded sender addresses.
Mailing Lists – Dedupe
SMTP Service – Delivery – Dedupe email messages option now also works for mailing lists. If user is subscribed to mailing list under multiple aliases, IceWarp Server will check for duplicate message to the same user and only deliver one of them.
Rules – Move To Folder
Move To Folder support for non-user accounts added, useful in Groups and direct delivery to a specific folder (instead of Inbox).
Rules – Date/Time Criteria
The rules engine has been extended with ability to define user rules based on time conditions, same as already available for content filters. Users might want to forward incoming emails or SMS messages only on weekends for instance.
Content Filters – RegEx Rewrite
Lets create new results using part of the search pattern.
Content Filters – DNSBL
RegEx is used instead of string match which was capable of wildcards only, now allows direct server match, RegEx field added in Administration GUI.
Content Filters – Edit Message Headers
Support for RegEx and RegEx rewrite, even for Delete action (must match the header value)
Content Filters – SmartAttach
Perform SmartAttach action based on any condition, such as attachment size, sender, domain etc.
Content Filters – Recipient, Cc, To, Attachment Conditions
Beside the previous global string match (which converts multiple addresses to string and matches that string), it's now possible to choose whether to match all items, or match at least one item from the string, to apply the condition "per item".
Content Filters – Unicode Filenames
Support for Unicode filenames when extracting attachments to directories (for SmartAttach and others, Anti-Virus remains AnsiString because external filters could not handle Unicode).
Content Filters – Apply Before Copy Incoming/Outgoing
Possibility to apply content filters before the copy operation in Management – user – Mailbox - Copy incoming mail, Copy outgoing mail actions. Original email recipients are saved during Copy incoming/outgoing mail actions and can be used in new %%bcc_recipients%% server variable.
Email Address Extension
Email address extension supported again, e.g. e-mail to john:%%MyFolder%%@mydomain.com will be delivered to folder MyFolder. Only works for emails not tagged as spam, trusted hosts, whitelisted or otherwise bypassed recipients.
SMTP – Traffic Limits
SMTP outgoing queue processing is delayed for low user licenses and high traffic, receiving works normally. Considers amount of incoming and outgoing emails to non-local accounts per day with relation to the number of licensed users. If the number of outgoing exceeds a threshold, sending out will be postponed for some time, until the levels balance or 12 AM. The limitation never occurs for 200+ user license, very seldom occurs for 100+ user license, and mostly occurs for less than 50 user licenses. Prevents using low user licenses as filtering gateway and for large mailing lists.
