Collax E-Mail Archive: Reorganite Indexing

A re-structured indexing of the mail archive data enabled RAM memory usage to be lowered. The change affects only complete re-indexing.


E-Mail: Increased required space when using IMAP and full-text index

The option “Generate full-text index” in the options of the dialog “Mail and Messaging -> Mail Storage -> IMAP and POP3” generates a full-text index of the local IMAP folders which accelerates the search within the IMAP folders and e-mails. While activated, the system could use up to 20% more space compared to the former release (also with activated index) for the service cyrus. Please check the space requirements of the service cyrus in advance. Under the dialog “Status -> System -> Statistics” the graph “filesystem/data” shows further details.

E-Mail: Collax Virus Protection powered by Kaspersky prior Version 7

Version 7 of the Collax C servers has updated the anti-virus engine and the format of the patterns. This was done to respond to new threats with the best possible protection.

All installations using the Collax Virus Protection module should therefore, be brought up to date.
