Microsoft Outlook keeps sending messages (Outbox is empty!!)

[Guest]

I've just started working with Microsoft Outlook 2003 and Business Contact
Mgt. The problem is I can receive mails from my POP3 server, but can't send
them through my SMTP server. HTTP is working fine.
Also, Microsoft Outlook status bar shows it is constantly sending out
messages, but there are none in my Outbox. What is it sending out?

The main causes of this are two: one is that you're not properly
authenticating to the outgoing server and the other is that you're using a
program like an antivirus app to scan your outgoing mail.

Probably an undelivered read receipt. See this:
