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
thats not something roundcube has any control over. roundcube is an IMAP client nothing more. routing like that is going to be up to your MTA.
