But they cannot send the email directly to the destination mail server. First their mail client does not know which destination server is responsible for the recipient (hint: DNS) – that functionality just is not built in. And second the user is likely assigned a _dynamic IP address_ which is blocked by most mail servers because they tend to get abused by infected Windows PCs that send out spam. So the correct way to send an email to the internet is through your mail server. This is called _relaying_ because your mail server acts as a relay. In this example your user wants to send an email to `fred@example.net`. -![](https://workaround.org/wp-content/uploads/relaying.png) - -![](https://workaround.org/wp-content/uploads/relaying.png) +![Diagram showing a user sending an email](images/big-picture-relaying.png) Relaying/sending email via the mail server diff --git a/src/content/docs/ispmail-bookworm/80-tls-certificates.mdx b/src/content/docs/ispmail-bookworm/80-tls-certificates.mdx index 5bb4b20..46fb270 100644 --- a/src/content/docs/ispmail-bookworm/80-tls-certificates.mdx +++ b/src/content/docs/ispmail-bookworm/80-tls-certificates.mdx @@ -209,7 +209,7 @@ systemctl restart apache2 Now when you point your web browser to **webmail.example.org**, your browser should tell you that it trusts the web site’s certificate: -![Browser bar showing successful encryption](https://workaround.org/wp-content/uploads/2018/01/Auswahl_063-1.png) +![Browser bar showing successful encryption](images/tls-browser-bar.png) (Yes, sorry, this is not **webmail.example.org**.
