Hi everyone. All email, inbound and outbound, both internally and externally has stopped working on our SBS 2008 server (Exchange 2007 I believe). All was working fine earlier today and yesterday. Then it just stopped working. I rebooted the server, and once back up, emails started coming through again. But now it's stopped again.

Can anybody shed any light on what would cause this? I have made no changes to the server at all.

Hi, other than rebooting the server have you checked a few other things such as, are all the services running? Check the event logs for errors and post any errors there are.

This is resolved now everyone. Two issues caused it.

1. The Microsoft Exchange Transport service kept stopping due to low disk space on the C drive of the server. Moving the page file to another drive sorted this.

2. Somebody had sent an email to a ton of people and clogged up the queue. It appears that this caused our ISP to temporarily suspend port 25 traffic from our IP address. I cleared down the queue using the Exchange Management Shell - Remove-Message -Filter {FromAddress -eq "user@domain.com"}.

As soon as the ISP were happy I'd stopped the flow, they opened up port 25 and all's well again :thumbsup:
