Information about the .z3 (z3) file type

Below is all the information we have available on file about the .z3 (z3) file type.

ZoneAlarm MailSafe quarantined file.

MailSafe was a feature which used to be included with ZoneAlarm for filtering both inbound and outbound emails for viruses, spam and other malware. Newer versions of ZoneAlarm no longer include inbound filtering (on the grounds that this is typically provided by most modern mail clients), but does still filter outbound.

A .z3 file represents a quarantined (inbound) email attachment. You should use ZoneAlarm to view the file.

Later versions of ZoneAlarm MailSafe used the file extensions .z4, .z5, .z6, .z7 or .z8 and earlier versions used .z1 or .z2 depending on the version of ZoneAlarm MailSafe being used.
