Why can't SourceForge send my outbound mail?

If you are unable to send email directly due to firewall restrictions, or if mail is being rejected by the application server's IP address, configure SourceForge to send outgoing messages through a gateway mail server.

Configure SourceForge to send outgoing message through a gateway mail server by adding the following to the <mailet match="All" class="RemoteDelivery"> directive in the configuration file at /usr/local/sourceforge/user/user-<version>/apps/user/SAR-INF/config.xml:

<gateway>smtp.example.com</gateway>
<gatewayPort>25</gatewayPort>
Note: The code is usually found on line 362 (commented out) of the configuration file.

If your gateway mail server requires authentication to send email, you may also add the following directives:

<username>username</username>
<password>password</password>
