The Remote SMTP Delivery page allows you to enable email services using a remote SMTP server when port 25 is blocked.
To configure the Remote SMTP server on your UCX system, perform the following steps:
- From the System tab, select System Tools
- From the Left Menu select Remote SMTP
- Update the fields as required
- Press the Save button to save the configuration changes
The fields required for the connection are:
| Field | Description |
| Status | Select ON/OFF to enable/disable connection to the SMTP server |
| SMTP Server | Select the type of email server to use: Other, Aol, Gmail, Office365, Yahoo, |
| Domain | Domain or Host name of the SMTP server |
| Port | Port to establish connection with the SMTP Server |
| User | User name of email account on the SMTP server |
| Password | Password of the email account on the SMTP server (if this account uses two-step authentication, you may need to request an App Password from your provider) |
| TLS Enabled | Check to enable authentication of certificates for Transport Layer Security. Some SMTP servers like GMAIL require this certificate. |
Gmail
If you have issues using a Gmail account, please see this product notice: Email Relay Using Gmail Account Fails Due to Bad Credentials.
MX Lookup
When entering the Domain name, if the name is entered within brackets [ ], MX lookup is turned OFF. For some domains, it could be important to turn OFF MX lookup to make this SMTP feature work (i.e. the brackets are required for proper functionality).
