1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to

4. Choose your deployment method:

choco upgrade fossamail -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade fossamail -y --source="'STEP 3 URL'"

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

FossaMail is an open-source, Mozilla Thunderbird-based mail, news and chat client for Windows and Linux, brought to you by the Pale Moon developers (and therefore not affiliated with the Mozilla Corporation). It is an alternative version of the Mozilla Thunderbird mail and news client, and based on the Pale Moon browser core.


  • Is built from source with compiler optimizations geared towards an as stable and smooth operation of the client as possible (Pale Moon-alike optimizations).
  • Uses the Pale Moon browser core as its back-end. The client is therefore based on Pale Moon rather than other Mozilla-derived mail clients.
  • Uses its own profile folder on your system. This means it will not interfere with existing Thunderbird installations.
    • The default profile location is %APPDATA%\FossaMail
  • Should be compatible with many Thunderbird add-ons and plugins.
  • Is available in 32-bit (x86) and 64-bit (x64) versions for both Windows and Linux.
  • Comes with an optional calendar/organizer integrated that will allow it to be used in a Microsoft Outlook style information manager fashion.


FossaMail is an English language client, and this package does not install any other languages. Go here for any available, alternative language packs and instructions. It is recommended to uninstall any language packs before upgrading to a newer version of FossaMail.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
