Run `mailrelay` on a local PC or server and set your device (e.g. scanner) to send mail to it.

`mailrelay` is written in Go, and can be compiled for any Go supported platform including Linux, MacOS, Windows.

`mailrelay` can be compiled for any Go supported platform including Linux, MacOS, Windows.

|

## Encryption
|
||||
|
||||
`mailrelay` uses TLS to connect to your SMTP provider. By default implicit TLS connections are assumed, meaning the connection is established
|
||||
using TLS at the socket level. This is in accordance with [RFC 8314 section 3](https://tools.ietf.org/html/rfc8314#section-3). These connections usually use port 465.
|
||||
|
||||
However, some providers do not adhere to this recommendation (I'm looking at you Office365!) and only support the legacy STARTTLS command, which expects a non-encrypted socket connection at first, which is then upgraded to TLS. To enable this, set `smtp_starttls` to `true` in your config.

To enable this, set `smtp_starttls` to `true` in your config. You may also need to set `smtp_login_auth_type` to `true` which enables the legacy [LOGIN authentication](https://www.ietf.org/archive/id/draft-murchison-sasl-login-00.txt) method.
