Configure mail settings in ColdFusion Administrator
Email support is a core requirement of most ColdFusion powered applications. Settings related to your mail server are managed here.
Mail Server Details
This section covers the basic settings required for the cfmail tag to function properly. You will need to configure the connection to your mail server and enter the appropriate authentication credentials.
Digitally Signing Emails
ColdFusion provides the ability to use digital certificates for signing outbound emails. Whether you implement this feature depends on your application's security requirements and email authentication needs.
Remaining Mail Server Settings
Key recommendations include: verifying your mail server connection, maintaining at least one backup mail server for redundancy, enabling "Maintain connection to mail server" for better performance, determining the appropriate connection timeout through performance testing, and enabling SSL/TLS encryption as required by your mail server.
Mail Spool Settings
It is recommended to determine the optimal spool interval and number of delivery threads through testing based on your mail volume. Always spool messages to disk for safety to prevent message loss during server restarts. Configure these settings according to your mail volume and network conditions.
Mail Logging & Charset Settings
The default mail logging level is set to "warning" which is appropriate for most installations. Avoid logging all messages unless absolutely necessary, as this can quickly consume disk space. You should also set the default character set for email messages, which is typically UTF-8 for international character support.
