Im runnign an exchange 2003 server, has been working fine but i currently have several hundred emails que'd up in the Local Delivery folder.
It was working fine up till about lunch time yesterday (around 20hrs ago)
The que are all on retry and some local/internal domain mail is going through but takes 5 to 10 minutes when its usually instant, but from what i can see all incoming external mail or 95% of it is sitting in the que as well.
Also seems outgoing external email is not going through or is being heavily delayed as well.
Has anyone got any idea's or suggestions of why the server would stop delivering its email to the mailboxes?
