Hi, apologies if this is in the incorrect group. It's my first post here. My company uses an X400 connector to send sensitive data to a third party (who in turn attach additional information to the msg before sending it on) Our company servers are in one routing group, the third party is in a seperate RG connected via X400. Our problem is, when link state information is passed down this connector to the remote MTA, it interperets this message as bad and therefore rejects the message which in turn causes various flags to pop up and alerts generated. (We are a security conscious company. Every alert gets investigated) I understand the need to update link state info, yet we also need the X400 connector. Is there any way to inhibit what info goes down the connector, (which will not get interpereted as a bad message) or do I feel a software patch coming on from the third party!! Thanks for any help.
