Postfix not communicating with Mail server
Please I need help urgently.
My postfix mail server has stopped sending out mails. users on the network cannot send mails to other users on the same domain and even to other domain. I use postfix and fetchmail services on my mandrake linux. I have never experienced this before. When I do mailq it gives the following error 'server refused mail service', but I receive mail from other domain.
Could this be a local problem or that of our domain mail server?
Please help
