S/MIME Encrypted Email Example with Gmail and Comodo

A quick how-to installation for secure S/MIME installation for a Gmail account on macOS. This certificate can be used to simultaneously encrypt and sign emails.

Obtain and install an S/MIME Certificate

  1. Create a unique revocation passphrase in a password manager—long, random, unique.
  2. Browse to Comodo and request a free, secure email certificate:
  • Enter your name, email address, and specify the maximum 2048 bit length
  • Enter your revocation passphrase in case your private key is ever stolen or compromised

How to Migrate, Rebuild, and Fix OS X Server

I upgraded my server to new hardware, hand-migrated all its data, and fixed Profile Manager’s “500 Internal Server Error” problem. My experience has been the same as the Ars commenter who wrote that OS X Server is “extremely fragile, and when it breaks it breaks severely and inscrutably.”

The online documentation to rebuild and/or fix OS X Server is sparse and inadequate, so I’ve posted my ultimately successful steps here.

create calendarserver
sudo enable for calendarserver
sudo -iu calendarserver
git clone https://github.com/apple/ccs-calendarserver.git
echo "source CalendarServer/environment.sh" > .profile
cd ccs-calendarserver
export USE_OPENSSL=1
sudo ./bin/package /Users/calendarserver/CalendarServer

SMIME Certificates Signed By OD CA

Here are my notes on how to create S/MIME Certificates signed by OS X Server's Open Directory Certificate Authority. It's pretty easy to set up your own small-scale PKI on OS X Server using the OD CA, which will already be a trusted CA.

Step Zero:

Make sure that you have OS X Server's Certificate Authorities installed on your local admin account:
