- Are you leaving the credentials blank in the Send panel?
- Using "Authenticate with POP3 before send"?
- are you sure you are pointing SMTP at the right server/port? I ask
  because my provider has different servers for different account levels
  -- my main mail goes to a secure server, while some of my other lesser
  accounts go to a normal, less secure server. In addition, the secure
  server even uses a very non-conventional 4-digit port.



BTW, this is the .signature file I used circa 1990 after several years
involved in the Internet's early deployment days:

   "Until you've found AND fixed a problem, 
    what you discount will likely be the source."

That was my way of saying the most difficult problems usually have a very
simple/subtle cause which is/was too "unlikely" to take seriously... :) :)

Good luck,
