File extension PMO description:
Any file with this suffix is either a saved messages to return to at a later date, or a message saved as stationary. You can save any message you are working on, by pressing ctr-s. The messages are given the name "content of the To: field, content of the Subject: field". Up to the 3.0 version there is no visible difference between a message saved as stationery and a normal saved message (Stationary is indicated by a flag [SY=1] inside the *.pmo file itself). Within the 3.0 version the draft window will display whether or not the message is an AutoSave, draft or stationary message.pmo
