Hello, I need someone wich configure me per Teamviewer my Plesk-Server. I will sent mails over antispam-europe as a relay. I also setup under the [login to view URL] the following entry: relayhost = [login to view URL] OS: Linux Ubuntu / Debian Latest Plesk SSH Access via my Teamviewer Project-Target: I will be able to sent out a mail via my antispam-europe server ([login to view URL]) for all my domains, as a example domain we will use [login to view URL], wich is preconfigured.
