Error when sending emails

[DanB]

Hi There

I just installed RC on hMailServer.

Every time I send an email from RC I get an error.... Error writing data (or something like that).
The emails IS sent, and it arrives at the reciepient, but why the message???

As Far as I know the log and temp folder is writable, as I can see a logfile is created in the log folder (nothing is in the temp folder).
