E-mail / Spam Issues

Q2. Why does ThunderBird freeze when sending and receiving e-mail?

This could be caused by large scan times of mailboxes. Please try the following:

• Excluding the mailbox folder from real-time scanning:
  1. Open F-Secure Internet Security.
  2. Click the Virus & Spy Protection tab and then ‘Advanced…’. The Advanced dialog appears.
  3. Click ‘Real-time Scanning’ on the menu list.
  4. Click the ‘Exclusions…’ button (on the bottom right corner). The Exclude From Scanning dialog appears.
  5. Click the ‘Objects’ tab.
  6. Tick the checkbox ‘Exclude Objects (files, folders...)’.
  7. Click the ‘Add’ button and browse to the folder you want to exclude.
  8. Click ‘OK’ to confirm your selection. You can now close the dialog windows.
  9. The object you have selected and all its contents will be excluded from real-time scans until you remove it from the Exclusions list.
• Check that your Internet Shield firewall level is set to ‘Normal’.
• Check that Thunderbird (Tools -> Account settings) is not copying mail to a local folder.
