Hmmm... do you understand what is POP3? Your post describe something like IMAP problem not POP3. If it is POP3 then it works well.
Maybe write more clearly cause it is hard to understand... once you write 'mobile', the second time 'laptop'.
Sorry if its was not clear. Let me give one example
a. I have Email A on my server and its downloaded onto mobile.
b. I downloaded this email onto my outlook (laptop). Right now there is no email on the server.
c. I have switched off my laptop
d. I have received Email B. This exists on my server at the moment as my laptop is off
e. Now my Aquamail is again sync with Server. It downloaded email B. Email A is not deleted from mobile as "Purge is only when the mail server is empty"
f. The email is sterile. Because i configured as download headers only mode when i am clicking on more details its unable to fetch as its obvious that email doesnt exist in my server.
g. To delete this email A, i have to wait til next sync when there are no emails on my server otherwise need to delete it manually.
Hope this is clear now
Thanks,
Vikram
