With the recent heartbleed SSL vulnerability, FastMail have updated their SSL certificates. Here's how to download the certificate and convert it into PEM form.

Find out which certificate you need:

% msmtp -a fastmail --tls-certcheck=off --tls-trust-file= --serverinfo

Download the certificate:

% curl -O https://www.digicert.com/CACerts/DigiCertHighAssuranceCA-3.crt

Convert it into PEM format:

% openssl X509 \
> -inform DER -in DigiCertHighAssuranceCA-3.crt \
> -outform PEM -out DigiCertHighAssuranceCA-3.pem
