Sent emails are not always received, but appear ok in my Outlook?

[Guest]

Sometimes, but not always, when I send messages through Outlook, they appear
to be sent okay (show up in my "sent" box). But, they are never received by
the addressee? I have tried "read" receipts, but if the message doesn't go
through, I obviously just don't get a read receipt. What could cause this
intermittent problem?

Lots of things.
On clients side of the sender it could be the ougoing virusscanner causing
this.
In between it could be various virusscanners, junk e-mail scanners and
misconfigured mailservers causing this.
At the receiving end it could be just about everything :-D

Does anyone have a suggestion for the most likely culprit that I could check
and hopefully fix?
