Two-factor authentication: acceptance of the next token

Mail: IMAP4FLAGS Sieve Extension IMAP service added

With this release the imap4flags Sieve Extension has been added to the IMAP service Cyrus.

Backup: Sender domain for status messages

Previously, backup status messages were sent to the e-mail address entered here, whereby the sender was also identical. In future, a suitable sender domain will be searched for, similar to “cron” scripts, and “backup” from this domain will be used as the sender.

Issues fixed in this version

Mail: Hostname mismatch with encrypted collection

When fetching emails via encrypted connections, the error “Server certificate verification error: Hostname mismatch” occurred in the system log of the fetchmail service. This was caused by an incorrect interpretation of a dot at the end of the server name when checking the server certificate. This problem has been fixed in the current release version.

Notes

Additional software: Bitdefender - Proxy for updates

The virus pattern updates are carried out according to a set cycle. It is currently not possible to use an http proxy for the pattern update of the Bitdefender virus and spam filter.

Additional software: Bitdefender - pattern update after commissioning

After starting up the Collax Antivirus powered by Bitdefender module, it may take a few minutes for the current virus patterns to be downloaded. If you click on Update Bitdefender in the virus scanner form during this time, you will receive an error message “Error connecting to server at /opt/lib/bitdefender//bdamsocket: -3”, because the background process has not yet been fully executed.

GUI: Sporadic hangs during running jobs

The progress of configuration jobs is displayed in the top right-hand corner of the web administration. In the case of extensive changes in the network area, especially with country locks (geo-ip), it can happen in rare cases that the job display hangs during activation. As of release 7.2.28, you will now receive the message “Network connection has been interrupted: Messages may be lost until the connection can be re-established.” informs you about such situations.
