Hi,

it’s me again, from [CRAM-MD5 Authentication for mail](https://meta.discourse.org/t/cram-md5-authentication-for-mail/47442).

I now need to authenticate to POP3 with CRAM-MD5, but the configuration does not expose that option.

```plaintext
2016-07-23 23:37:48 pop3-login: Info: Disconnected (tried to use unsupported auth mechanism): user=<>, method=PLAIN, rip=82.*.*.*, lip=78.*.*.*, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)

```

Best regards, hexa
