Hello, I have one RHL 8.0 server with postfix installed that will relay all emails to domain xyz.com to internal mail server. Configuration: in main.cf: relay_domains = $mydestination, xyz.com and in transport xyz.com smtp:internal.mailserver.com So far it works. I can receive all emails from outside in internal mail server. My question is, if the connection between postfix server to internal mail server is lost, will postfix keep the emails and resend it again after the connection restored? Or postfix will bounce the emails back as undelivery or else? -- Best regards, Budi Febrianto (mailto:bfebrian@xxxxxxx) -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
