| Code Block | ||
|---|---|---|
| ||
'email' => {
'mail_domain' => 'yourdomain.com',
'mail_from' => 'yourmailname@yourdomain.com',
'mail_password' => 'your_password',
'mail_server' => 'smtp.yourdomain.com',
'mail_server_port' => 25,
'mail_use_sasl' => 'false',
'mail_use_tls' => 'true',
'mail_user' => 'your_user_account@your_domain.com'
}, |
Find Open opCommon.nmis in an editor, find the email section in opCommon.nmis and update the values to match the email server that opEvents should utilise.
Here is a brief description of the fields:
| Field Name | Description |
|---|---|
| mail_domain | This is required for some mail servers that enforce strict HELO messages. Using your company domain here is a good idea. |
| mail_from | This is the From address for email notifications. Emails will go out with this as the sender. |
| mail_user | This is the mail user name for authenticating at your mail server. Leave this blank if you don't need to authenticate at your mail server. |
| mail_password | This is the password for authenticating at your mail server. Leave this blank if you don't need to authenticate at your mail server. |
| mail_server | The FQDN (or IP address) of your outgoing mail server. |
| mail_server_port | The port number your mail server listens on for SMTP conversations. Common choices are 25 and 587, but note that 587 commonly requires authentication! |
| mail_use_tls | If you select true here, then opEvents will try to negotiate STARTTLS encryption with your mail server. Not useful if your mail server is localhost. |
| mail_use_sasl | disregard: deprecated, should not be present in new installations. |
