Configuring the Edge SMTP server

An SMTP server allows the Edge UI to send emails. For example, the Edge UI can send an email to assist a user in recovering their UI password.

At install time, you can specify the SMTP information. To change the SMTP information, or if you deferred SMTP configuration at the time of installation, you can use the apigee-setup utility to modify the SMTP configuration.

You can change any or all of the following information:

SMTP host, such as smtp.gmail.com
SMTP port, such as 465 if you are using TLS/SSL
SMTP username and password
SMTP "From" email address

To update the SMTP information:

Edit the configuration file that you used to install Edge, or create a new configuration file with the following information:

# Must include the sys admin password
APIGEE_ADMINPW=sysAdminPW
# SMTP settings
SKIP_SMTP=n
SMTPHOST=smtp.example.com
SMTPUSER=smtp@example.com  # 0 for no username
SMTPPASSWORD=smtppwd       # 0 for no password
SMTPSSL=n
SMTPPORT=25
SMTPMAILFROM="My Company <myco@company.com>"

Run the apigee-setup utility on all the Edge UI nodes to update the SMTP settings:
```
/opt/apigee/apigee-setup/bin/setup.sh -p ui -f configFile
```
The apigee-setup utility restarts the Edge UI.
