Only if all recipients are known will the e-mail be accepted and forwarded. For verification, an SMTP connection is established and the recipients are queried using the RCPT-TO command.

Issues Fixed in this Version
Security: Important security relevant System Components
This update will also install/update the following important system components:
- SQLite 3.26.0
- strongSwan 5.7.1
For self-monitoring of the system, Nagios monitoring is installed. The behavior of the Nagios notification was incorrect and generated incorrect alerts when the server was configured to not respond to ICMP echo requests (ping). With this update, a meaningful detection takes place and no unsettling warning messages are sent.
Collax Information & Security Intelligence: Report as PDF period wrong
There are a number of ready-made reports available. If you view a report in the browser, the set period is taken. However, if you download the report as PDF, the period is always set back to 7 days. This will be fixed with this update.
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. Patterns for versions prior to 7.0.0 will be available until December 31, 2017. From 01.01.2018 Kaspersky will not update the patterns for Collax version 5 and older. All installations using the Collax Virus Protection module should therefore, be brought up to date.
E-Mail: Release already deleted emails in IMAP mailboxes
In the dialog “Mail and Messaging -> Mail Storage -> IMAP and POP3” the IMAP server can be activated for the users to get access to their IMAP mailboxes. Due to a modified standard directive within the Cyrus IMAP mail server since the release V7, e-mails already deleted by the mail client have not been completely released from the harddisc. Since release 7.0.22, cyr_expire will free up memory for already deleted emails. Please note that already after restarting the IMAP service during the update, the process is started and proceeded after restarting the server and thus start the IMAP service.
E-Mail: Collax Avira AntiVir prior Version 7.0.24
Version 7.0.24 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. Patterns for versions prior to 7.0.24 will be available until December 31, 2018. From 01.01.2019 Avira will not update the patterns for Collax version 7.0.22 and older. All installations using the Collax Avira AntiVir module should therefore, be brought up to date.
Collax Information & Security Intelligence: Modified mapping of the indices
When updating Elastic Stack to 6.4.0, the mapping of the indexes was changed. This prevents Filebeat to write the data to the same index before and after the update. Therefore, after the update has been performed, the resulting data will no longer be included in the index. From 0:00 clock on, Elastic Stack will create a new index and all data from this point will be written again to the index. The data between the end of the update and midnight will be lost. If it is better to renounce to the data before the update, from 0:00 until the end of the update, the index for the current day can be deleted after the update via the administration interface. Then all data will be lost after 0:00 and the deletion of the index.
Collax Information & Security Intelligence: Schema change
A schema change in Release 7.1.0 requires that the elastic stack and beats be updated at the same time. To do this, update the server with the elastic stack and the server with the filebeats one after the other.
