Issue



You emailed a file that you compressed with WinZip version 10. When that file passes through Symantec Mail Security 5.x for Domino, you see one, or more, of the following messages in the Lotus Domino Server window or in the NAVTASK files:

“SMSDOM detected the Scan error (Unknown Error) in database Mailbox, document , author , component The document was QUARANTINED.

"SMSDOM detected the scan error (Unknown container algorithm) in database Mailbox, document author , component . The document was QUARANTINED."

You may also see messages in the SAVLOG.NSF under Statistics > Scan Error > Violation

You can open the file with WinZip 10 so you know that the file is not corrupt. You are unable to open the .zip files with other zip utilities.
