Hi, I have discovered some kind of bug in e-mail scanner. This bug causes total damage of recieved e-mails. Recieved e-mails are empty. Sometimes, form unknown reasons, operating system denies access to temporary folders (stored in TEMP and TMP system's envirnoment variables ). Reasons of that are not important unlike behavior of NOD's e-mail scanner. When e-mail scanner is receiving messages and it has no place to store it temporarly user receives empty e-mails. In the same time, when e-mail client recieved this empty message it requests to server to delete orginal messages from e-mail acconunt. So user stays with nothing. I have lost few important e-mails in this way, because I didn't realize that NOD32 has problems with access to temporary place. I think, that scanner engine should have internal safety mechanism to prevent e-mail client from delete messages from server, when scanning process cannot be completed (i.e. cause of problems with temporary place on disk). Think about it and improve your software. Thanks.
