I'm working on moving from PMTA over to Postfix and had a question on relaying for virtual domains. We send mail on customers' behalf and one of the things I'm trying to figure out is how to implement PMTA's "virtual-mta" in Postfix. This defines the destination host and credentials for the relaying. For example each of these would be their own respective config file:
<virtual-mta smtp.office365.com-39-95002> <domain *> route smtp.office365.com:587 auth-username "USERNAME" auth-password "PASSWORD" use-starttls yes </domain> </virtual-mta> <virtual-mta smtp.gmail.com-935-93737> <domain *> route smtp.gmail.com:587 auth-username "USERNAME" auth-password "PASSWORD" use-starttls yes </domain> </virtual-mta> We have a lot of these; one per customer. Is this possible to do in Postfix? Thanks!
