Automatic outgoing messages from our website (hosted locally) are using local SMPT while our email domain is hosted with MS OFFICE 365. We either need to set up a relay or other solution so that these web messages do not get flagged and quarantined by our mail reciepients with advanced security.
Our website uses port 25 and no encryption. Our worry is that recipient's email gateways are not seeing our outgoing web messages as legitimate since it is not coming from our proper email domain.
Our local IIS does not seem to have the settings necessary to accomplish what we are trying to do.
