<p>I would have to research what the others are although you can do this yourself using Han's guide to Pegasus Mail filenames and extensions.  Find it at: http://www.vandenbogaerde.net/pegasusmail/pf_pmfiles.html </p><p> </p>

<div><p class="MsoNormal"><span lang="EN-US">I found a strange bug in Pmail. There is an “undeletable” queued mail. (Look at the attached pegasus.png file.) When I close Pmail program it say me that I have some queued mail (panel 1). And indeed I can see it in Queue Manager (panel 2). I delete this queued mail (panel 3) but if I close Pmail program the alert about "not sent mail" appears again (and the same “undeletable” mail appears in Queue Manager again too). So, how to fix this problem?<o:p></o:p></span></p></div><div> </div>[URL=http://fastpic.ru/view/85/2016/1215/94cf2ee817a9159dc2988c66e3f0dded.png.html][IMG]http://i85.fastpic.ru/thumb/2016/1215/ed/94cf2ee817a9159dc2988c66e3f0dded.jpeg[/IMG][/URL]

<p>With Pegasus Mail closed, delete all zero length .PMO, .PMX and .PMW files in your Home mailbox directory. A backup of the Home mailbox directory before starting would be prudent. </p><p>If you don't know the location of your home mailbox directory go to Help | About Pegasus Mail then click the Info button.</p>
