/**
|
|
* Here's an example showing how to connect to the IMAP server with STARTTLS.
|
|
*
|
|
* The only difference is calling `starttls()` on the `ClientBuilder` before
|
|
* initiating the secure connection with `native_tls()` or `rustls()`, so you
|
|
* can connect on port 143 instead of 993.
|
|
*
|
|
* The following env vars are expected to be set:
|
|
* - IMAP_HOST
|
|
* - IMAP_USERNAME
|
|
* - IMAP_PASSWORD
|
|
* - IMAP_PORT (supposed to be 143)
