Is the sender getting any error messages or do the emails just disappear after Echange have received it?
I notice that you have a local IPv6 address, are you using IPv6 ?

No I am not using ipv6, and really strangely no error messages or ndrs from senders

U r getting the same result in OWA also..?
Or in Outlook..?
If Outlook its may he due to rules...

Pradeep

if i try to telnet into port 25 when i put in the dender address it is also giving me a invalid parameter?

And have you tried to send yourself an email from the outside and all mails to the inside users are just disappering ?

ASKER

yes

And can you tell more about the enviroment, servers, roles, AV/antispam solutions?

I also reccomend that you try the tools here: https://www.testexchangeconnectivity.com/

Also check wether the public ip is blacklisted or not using Mxtoolbox.com.
As mentioned once check the remoteconnectivity once.
Check whether any mails are stuck in the queues.
