Pegasus Mail, developed by David Harris, is an email client for Microsoft Windows. A PM4 file stores the program's general filtering rules, which define how Pegasus Mail handles messages that meet specified conditions.
This is a Pegasus Mail settings file rather than a document intended for independent use. It belongs to the program's filtering configuration and is read by Pegasus Mail when the relevant mail settings are used. The format is specific to Pegasus Mail and is not a general-purpose data format.
Open a PM4 file through Pegasus Mail on Microsoft Windows. The file is normally used by the program as part of its filtering configuration rather than opened directly from File Explorer.
If Pegasus Mail does not recognise the file, it may not be in the program's expected configuration location or may belong to a different Pegasus Mail installation.
A PM4 file cannot usually be converted to a common file format because it stores Pegasus Mail filtering settings. To move the rules, use Pegasus Mail's own filtering or configuration features when available, or recreate the rules in another email program manually.
