+# SMTP Rake tasks **(FREE SELF)**
+
+[Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/67802) in GitLab 14.2.
+
+The following are SMTP-related Rake tasks.
+
+## Secrets
+
+GitLab can use SMTP configuration secrets to read from an encrypted file. The following Rake tasks are provided for updating the contents of the encrypted file.
+
+### Show secret
+
+Show the contents of the current SMTP secrets.
+
+**Omnibus Installation**
+
+```shell
+sudo gitlab-rake gitlab:smtp:secret:show
+```
+
+**Source Installation**
+
+```shell
+bundle exec rake gitlab:smtp:secret:show RAILS_ENV=production
+```
+
+**Example output:**
+
+```plaintext
+password: '123'
+user_name: 'gitlab-inst'
+```
+
+### Edit secret
+
+Opens the secret contents in your editor, and writes the resulting content to the encrypted secret file when you exit.
+
+**Omnibus Installation**
+
+```shell
+sudo gitlab-rake gitlab:smtp:secret:edit EDITOR=vim
+```
+
+**Source Installation**
+
+```shell
+bundle exec rake gitlab:smtp:secret:edit RAILS_ENV=production EDITOR=vim
+```
+
+### Write raw secret
+
+Write new secret content by providing it on STDIN.
+
+**Omnibus Installation**
+
+```shell
+echo -e "password: '123'" | sudo gitlab-rake gitlab:smtp:secret:write
+```
+
+**Source Installation**
+
+```shell
+echo -e "password: '123'" | bundle exec rake gitlab:smtp:secret:write RAILS_ENV=production
+```
+
+### Secrets examples
+
+**Editor example**
+
+The write task can be used in cases where the edit command does not work with your editor:
+
+```shell
+# Write the existing secret to a plaintext file
+sudo gitlab-rake gitlab:smtp:secret:show > smtp.yaml
+# Edit the smtp file in your editor
+...
+# Re-encrypt the file
+cat smtp.yaml | sudo gitlab-rake gitlab:smtp:secret:write
+# Remove the plaintext file
+rm smtp.yaml
+```
+
+**KMS integration example**
+
+It can also be used as a receiving application for content encrypted with a KMS:
+
+```shell
+gcloud kms decrypt --key my-key --keyring my-test-kms --plaintext-file=- --ciphertext-file=my-file --location=us-west1 | sudo gitlab-rake gitlab:smtp:secret:write
+```
+
+**Google Cloud secret integration example**
+
+It can also be used as a receiving application for secrets out of Google Cloud:
+
+```shell
+gcloud secrets versions access latest --secret="my-test-secret" > $1 | sudo gitlab-rake gitlab:smtp:secret:write
+```
