In accordance with my POP3 settings (using Outlook Express), a tag is appended to all incoming emails (port 110). Until today this task was faithfully accomplished. However, today I received some mails all from the same sender with pdf's attached, and the tag was not appended. Maybe they were from a 'secure' server as the contents are 'private and confidential'. Is there any way to find out why the tag was not appended - perhaps from the message internet header details ? The top toolbar, 'File','Edit', 'View' etc. was not displayed in Acrobat Reader with these pdf's. Am also using Frontgate which I use to check mails on the server before downloading them. My 10th day of using NOD32 - please accept my apologies if this turns out to be some oversight on my part. Thanking you.
