Exchange 2010 - Back Pressure
Have come across a problem which has me confused (not a difficult occurrence to be fair). Please understand that my knowledge of Servers is somewhat limited and have adopted this, and have never built a server.
1) I have a Linux Mailserver feeding into an Exchange 2010 Server.
2) Recently i started having mail flow issues and they would hold on the Linux server and not be delivered. I dug up a variety of errors and have arrived at the conclusion that i have an 'Exchange Back Pressure' issue which is, based on the event logs, due to insufficient disk space. However, the partition where my Exchange is installed has 2.5GB of space.
3) There appears lots of information about what the causes of 'Back Pressure' are but, nothing very definitive on how to resolve it. Do i need to buy Easeus and resize my partitions? Even when their appears to be space available.
One thing i have discovered is that after a restart of the server, i buy myself about 3-4 days where everything works fine again.
Any help or advice on this would be excellent. Thanks in advance.
