Sorry meant to say Pondus instead of Logos...

email is sent, funny thing is when I tried to send the "original" infected email to virus@avast.com, it sent the email without warning but while uploading to my mail server's "sent item" folder, Avast found the threat and removed the attachment. Checking my "sent items" folder on my mail server shows the message without attachment.
So now the question is not only why didn't the Avast email scanner catch the infection when I first received the email or even when I sent it to virus@avast.com??? But why DID it catch it when sending to my Apache mail server?
