Issue with SBS2008 Sending email out on a Dell PE2900
Mail would receive just fine into the SBS2008 however sending email out would get stuck halfway and never get delivered.
No Return Bounce NO indication of any issues.
Found out that Broadcom NIC was the issue in the Dell PE2900
Even though it had Version 9 drivers Dell claimed that version 12 “Might”
I repeat “MIGHT” work.
Instead of dealing with it not working after new drivers, I disabled Onboard NICs
Purchased a DLINK 1GB Nic Card.
Installed and mail going out correctly now with no issues!
