Hi everyone, I have a problem with Nethserver, I'm trying to set up two separate mail servers, one manages an aruba domain, the other one must manage some libero.it accounts.
My intent would be to configure the servers via the pop3 connector and its smarthost, since after creating users, set the mailboxes, and enabled pop3 connector, on the aruba domain i have no problems, i just had to configure stunnel for the smarthost ( NS6.9) and receive and send it to any domain without any problems. The problem arises with the libero.it domain, in fact, after performing all the procedures like for the aruba domain, I quietly download the mail, but if I try to send an email from the server that manages the libero.it domain to a libero account. Which is not configured on NS, I receive: "550 5.1.1: Recipient address rejected: User unknown in virtual mailbox table". If I try to send to a domain that is not free.it, the message is part and is delivered normally.
Could it be a DNS problem? If so, could you please tell me how to solve the problem? thank you so much.
