Paid on delivery
[repost - issue not fixed, got sidetracked] On a Ubuntu 20.04 Linux webserver running Webmin and Postfix/dovecot, outbound mail routing is broken. Outbound mail is not reaching recipients. Server is self-hosted. Need to establish correct inbound and outbound routing using ISP relay [or, if not possible, some other affordable way]. Solving for 2 use cases: 1) Mail originates from the server itself (stats, error alerts etc.) and goes to an external recipient (e.g. Gmail) 2) End user is using web mail client to compose/read email, such as Horde or Roundcube. Roundcube is hosted on this same machine. Email composed by the end user needs to go out and be delivered to external recipients I will provide screen sharing access to a Windows machine (Anydesk or another method if needed) that has Putty with SSH sudo access to the server. Screen will be recorded.
