Hello Roudcube community
I have an exchange, which mainly handles the mail-flow.
I set it up to relay messages, where the mailbox is not on the exchange, to a Linux machine with roundcube (plesk).
This works without a problem except for the return way.
When I send a mail from roundcube to the exchange, it's searching for the mailbox on roundcube, and cannot find it.
Is there a way to configure roundcube like the exchange?
Like: "If mailbox not here, send it to exchange"
Thank you very much
