My internal email is being blocked/delayed...need help figuring out how to fix it.
Here is my network config;
Windows 2003 Native Network 2 DCs
1 Windows 2003 Member Server
12 Win 2000 desktops
12 win XP desktops
1 Watchguard firebox x500
Symantec Antivirus Corp 10.01 having problems upgrading to 10.1 ( this is where I think the problem is)
I can send emails from the internet but sending from my client emails seem to go out but never reach their destination. Emails internally never reach their destiantion either. Problem is system wide.
