Hi,
I have a very annoying issue. I want to use my own Exchange Server but unfortunately it rejects the first command when I connect it.
The issue is described here:
Microsoft KB
and here
Serverfault.com
The point is, I don’t have the mentioned firewall/switch. I have an HP switch and a SonicWALL. I don’t find any help.
Is there a workaround I can hack into your source code? The very strange point is, the 1st command is rejected, then, I can use EHLO <servername> without any problem.
So, the hack should ignore the first command and then it continues with the normal code.
When I try to connect behind the firewall then it works so I suspect the SonicWALL but DELL is not capable to help me. Accessing it behind the firewall but routed through the switch then it works as well. This means, the HP switch cannot be the problem.
Any chance? Any idea? Any suggestions?
Thx
