Hi,
I have a client with a four month's old SBS 2011 installation, running ESET for Exchange (2010). There's some strange things happening with email delivery, where an incoming email (from an external source) will be delivered to one mailbox instantly (~1 minute) but another user will get email four hours later, the sample email was sent to two different recipients.
I've never seen this behaviour on an SBS 2011, it's not like Exchange is under heavy load (10 users in the business) or the server underpowered (it's got 4 vCPUs and 32 GB of RAM assigned, running as a VM on top of Windows Server 2012 R2 Hyper-V).
Is there any way to check if ESET is responsible for these random delays?
Any help would be most appreciated.
