Secure website support: Let's Encrypt
What makes a website secure and why do I need it?
If a website is secure, it means that all information from the website to your computer is encrypted. This ensures a potential attacker can't steal your information.
Soon browsers will start warning you if a website you're viewing is not encrypted. Your viewers may not want to read your website if they think someone may be able to see what they're browsing. HTTPS is the secure version of HTTP. It's the procedure over which data is sent between your browser and the website that you are connected to. The 'S' at the end of HTTPS stands for 'Secure'
Browsers also show padlocks in the url bar to show that the website is secure. We do the same thing when you log into FastMail. Check the address bar for the green padlock badge with the text “FastMail Pty Ltd”.
Secure website support for custom domains
FastMail now integrates Let's Encrypt support to our domain and file hosting features. We will automatically generate a SSL certificate for your domain using Let's Encrypt.
Any website hosted at FastMail, with your custom domain, can be secured. In addition, any account administrator can enable secure website support.
If anyone chooses to access your website, they will be safe in the knowledge that their data transmission is protected.
How to secure your website
To enable Let's Encrypt for your website:
2. For exisiting websites, select 'Edit'
3. Check the 'secure' box.
4. Select 'Save Changes'
Note: For newly created websites, select the 'Secure' checkbox when configuring.
Renewing your certificate
The certificate lifespan is 90 days, but we will renew these automatically after 60 days to ensure that there are no service interruptions.
Secure websites for other domains
Currently we're unable to provide certificates for wildcard websites and websites on FastMail domains (such as fastmail.com). However, if you're not using your own domain and you've set a password on your site, you can access your files over an encrypted connection. This can be done by using the special address of the form below:
If we can't create or renew your certificate, we will e-mail you.
Potential DNS errors with Let's Encrypt
Note: As a DNS host, FastMail does not support DNSSEC.
There are two solutions available if you have DNSSEC enabled on your domain:
Amend your DNS host to a host who supports DNSSEC
Disable DNSSEC for your domain.
We configure the certificate on your behalf, but the only information we send to Let's Encrypt is your domain name: no other information is shared.
