I have a problem with multiple IP addresses:
My server has 2 IP addresses.
Another servers can use ZCS to relay mails on both Ip Addresses. But when the mails go out of ZCS, all mails use only one IP Address.
What I would like to do: if another servers send to one IP address, the mail go out with the same IP address by which they come in.
I hope I was enough explicit.
Someone have an idea?
