Yes. But it's not that what defines a web service. A normal HTTP request does 
give as well back status code about sucess (for example code 200) and failures 
(normally 4xx or 5xx codes). It's not that what defines a web service.

It's funny we talk again about web services and DSPAM. Tell me one mail client 
that does web services out of the box? Outlook probably can do web services 
with the help of IE. I for sure know that Lotus Notes Client can talk to a web 
service. Have coded a SPAM/HAM plugin for Lotus Notes Client that exactly that. 
But I used Lotus Domino as the web service provider and then communicated from 
Notes to Domino to DSPAM. But to bring the discussion back to the original 
topic: What mail client is capable out of the box to do web services?
