Hi guys,

Can anyone shed some light on this for me.

We have 3 E2k forests (companies), each with one domain.
Company a also connects to a fourth (company d) company using the groupwise connector.
Companies a and d have been connected for some time, and the other two companies have

recently be joined on.

People in company a have the primary email address x.y@company.co.uk
They have the secondary address x.y@company.com
People in company b have the primary email address x.y@company.com
They have the secondary address x.y@b.company.net
People in company c have the primary email address x.y@company.com
They have the secondary address x.y@c.company.net
People in company d have the primary email address x.y@company.com
They have the secondary address x.y@company.ch

All four companies are connected over a VPN.

We are using a directory synching tool to connect the E2K domains and then the directory is

replicated to the GroupWise system over the connector. All users from the foreign forests are

imported as contacts.

The main directory is held at company a and this server handles all the routing via SMTP

connectors. There is one SMTP connector for each company and points to b.company.net for

commpany b and c.company.net for company c.
When pulling directory entries TO company a, the proxy addresses are swapped with the

primary. This way exchange knows when it received a .com addressed message, to send it to the

correct *.company.net address (as this is now the contacts primary address) and this works

very well. When pushing the directories back out (company b contacts to company c, and

company c contacts to company b) the addresses are swapped back again, so they see the

address x.y@company.com as the primary address.

The only problem is as follows:

People in company a send an email to an external recipient AND an internal recipient.
The external recipient can then reply to the person from company a (x.y@company.co.uk) but

cannot reply to the person from either company a or b as the reply address is their secondary

proxy address of x.y@b.company.net or c.company.net respectively.

This also happens if someone from company d sends a mail to an internet recipient and copies

or includes someone from either company b or company c on the mail.

Does anyone know any way of preventing this???

Any advice/help would be appreciated!!

Eddster.
