4.1.2.1.1 Compatibility
Certain email programs may experience problems with POP3 filtering (e.g., if receiving messages with a slow
Internet connection, timeouts may occur due to checking). If this is the case, try modifying the way control is
performed. Decreasing the control level may improve the speed of the cleaning process. To adjust the control level
of POP3 filtering, from the Advanced Setup tree, navigate to Antivirus and antispyware > Email protection >
POP3, POP3s > Compatibility.
If Maximum efficiency is enabled, infiltrations are removed from infected messages and information about the
infiltration is inserted before the original email subject (the options Delete or Clean must be activated, or Strict or
Default cleaning level must be enabled).
Medium compatibility modifies the way messages are received. Messages are gradually sent to the email client.
After the message is transferred, it will be scanned for infiltrations. The risk of infection increases with this level of
control. The level of cleaning and the handling of tag messages (notification alerts which are appended to the
subject line and body of emails) is identical to the maximum efficiency setting.
With the Maximum compatibility level, you are warned by an alert window which reports the receipt of an
infected message. No information about infected files is added to the subject line or to the email body of delivered
messages and infiltrations are not automatically removed – you must delete infiltrations from the email client.
