Hi All,
Emails are retrieved twice (sometimes 3 times) from Qpopper vesion 3.1.2. 
I am using a netscape library to connect and retrieve emails. After retrieving email I 
mark it as deleted, it should be deleted after quit, but when I connect again the same 
email still in mailbox and I can retrieved again .... If any body kn ow why this is 
happen and if there's a way to know that the email is marked as deleted before 
retrieving it.
Thanks in advance
