Thanks for your prompt response and all your attention. I do in fact 
how eMail (sendmail in this case) works. What's more I run an RBL. 
However, having
seen all the attempts to foil Horde and friends in the last version. I have
become keenly aware of what is possible with *web*mail and the power of PHP.
So all my previous observations were based on that. When I noticed the 
in the "From:" display, a red flag went up. Noting that *normally* a colon
isn't permitted in a "safe" eMail. However, if Horde (IMP) is simply 
this "To:" to the eMail address. Than it is a different story. Is this 
the case?
This hasn't been clear.

Thank you again for all your time and consideration in this matter.
