# @file SendGrid Postfix Configuration
|
|
# @brief Configures Postfix to use SendGrid as a relay host so you can use the `mail` program to send e-mail from the command-line
|
|
# @description
|
|
# This script follows the instructions from [SendGrid's documentation on integrating Postfix](https://docs.sendgrid.com/for-developers/sending-email/postfix).
|
|
# After this script runs, you should be able to send outgoing e-mails using SendGrid as an SMTP handler. In other words, you will
|
|
# be able to use the `mail` CLI command to send e-mails. The following is an example mailing the contents of `~/.bashrc` to `name@email.com`:
|
|
#
|
|
# ```shell
|
|
# cat ~/.bashrc | mail -s "My subject" name@email.com
|
|
# ```
