Recently updated to the latest version and suddenly email notifications are no longer working.

Sidekiq has the following error:

```
obs::HandledExceptionWrapper: Wrapped OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=error: dh key too small

```

but I can’t seem to find much info on it that is at all useful.

My my configs are just the basic:

```
DISCOURSE_SMTP_ADDRESS: <smtp.domain.com>
DISCOURSE_SMTP_PORT: 587
DISCOURSE_SMTP_USER_NAME: <account@domain.com> 
DISCOURSE_SMTP_PASSWORD: '<password>'
DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)

```

(Urls redacted for privacy, its all just standard stuff though)
