Hi, I have a server that is and was serving well with qmail for years. Now one of the domains we're hosting on it is moving to Office 365, and so the updated DNS entries are like # host -t mx departingdomain.com departingdomain.com mail is handled by 0 departingdomain-com.mail.protection.outlook.com. departingdomain.com mail is handled by 5 my.currentserver.com. The idea is that, for a while, in order to make the migration smoothly, the current server should [continue to] work as a back-up server. For e-mail sent from wherever in The Internet, things are fine, _except_ for mails sent from within our LAN, for which - you guessed - my.currentserver.com is as well the company SMTP server. So mails sent from within the company are hitting the server and ... are delivered locally. Is there a way to make qmail try at first the external, higher priority MX, and deliver locally only if that one doesn't work? Many thanks in advance.
