<h1>Why do I need to install a certificate when configuring Apple Mail with Bridge?</h1>
|
|
<p class="standfirst">
|
|
Apple Mail requires a secure channel for communications with email servers, and the server needs to be acknowledged as trusted.
|
|
</p>
|
|
<p>
|
|
In order to communicate with Bridge, Apple Mail requires secure connections using SSL/TLS. This cryptographic protocol includes an identity
|
|
verification system using certificates. For publicly available servers, certificates are normally issued and digitally signed by a certificate
|
|
authority, such as Let's Encrypt. This is not possible for Bridge, as the IMAP and SMTP servers are running on your own computer, and are not
|
|
accessible from any network (local or internet).
|
|
</p>
|
|
<p>
|
|
The solution is to use a self-signed certificate. When setting up an email account where the server provides a self-signed certificate, most
|
|
email clients will issue a warning asking you whether you trust the server or not, because the certificate was not issued by a certificate
|
|
authority.
|
|
</p>
|
|
<p>
|
|
Apple Mail requires an extra step. It will simply refuse to connect if the certificate is not set as trusted. Bridge solves this by storing this
|
|
certificate in the macOS keychain. This operation requires that you provide your macOS account password.
