mail problems

[f.allinonesoft]

hi,

We have plesk 8.2.1 on a linux ubuntu 6.06 system.
Our problems are that our local mail doesn't seem to work.
Our mailqueue in plesk is full of local mails but they are stuck in the remote queue.
Sending mails from local to remote works and remote to remote also, but only the local to local is not working.

I hope some of you know a solution to this problem.

best regards,
