Hi Chris,
The problem lies in Qmailtoaster configuration that an administrator should do somewhere, and most likely and goes beyond, I suspect.
Earlier, the Qmailtoaster was wrongly configured, which Mustafa did not believe. You found that out. Because of this, I could not come close to certain trouble-shooting areas. Now this possibility is ruled out
Most likely it is no longer a problem in compilation or wrongly configured Qmailtoaster during compilation.
