RSpamd Error: Undefined Reference to ‘EVP_*’ – A Comprehensive Guide to Fixing this Frustrating Issue

Are you tired of dealing with the “RSpamd error: undefined reference to ‘EVP_*'” error message? Are you frustrated with the lack of clear instructions on how to fix this issue? Worry no more! In this article, we’ll dive deep into the world of RSpamd and OpenSSL, and provide you with a step-by-step guide on how to resolve this pesky error. So, buckle up and let’s get started!

What is RSpamd and Why is it Failing?

RSpamd is a popular open-source anti-spam software used by email servers to filter out unwanted emails. It’s known for its high performance, flexibility, and ease of use. However, like any software, it’s not immune to errors. The “RSpamd error: undefined reference to ‘EVP_*'” error occurs when RSpamd is unable to find the necessary OpenSSL libraries, specifically the EVP (Envelope Vault Provider) functions.

What are EVP Functions and Why are They Important?

EVP functions are a set of cryptographic functions provided by OpenSSL, a popular open-source cryptographic library. These functions are used for encrypting and decrypting data, as well as generating digital signatures. In the context of RSpamd, EVP functions are used to verify the authenticity of email messages and ensure their integrity.

The EVP functions are essential for RSpamd’s operation, as they enable the software to:

• Verify the authenticity of email messages using digital signatures
• Encrypt and decrypt email messages using SSL/TLS protocols
• Generate and verify cryptographic hashes

Causes of the “RSpamd Error: Undefined Reference to ‘EVP_*'” Error

So, why does RSpamd throw this error? There are several reasons, including:

1. OpenSSL is not installed or not properly configured
2. RSpamd is not linked against the correct OpenSSL library
3. OpenSSL libraries are outdated or corrupted
4. RSpamd configuration is incorrect or incomplete

Fixing the “RSpamd Error: Undefined Reference to ‘EVP_*'” Error

Now that we’ve covered the causes of the error, let’s dive into the solutions! Follow these steps to fix the “RSpamd error: undefined reference to ‘EVP_*'” error:

Step 1: Install and Configure OpenSSL

Make sure you have OpenSSL installed on your system. You can install it using your distribution’s package manager:

sudo apt-get install libssl-dev (Ubuntu/Debian)
sudo yum install openssl-devel (RHEL/CentOS)

Once installed, verify that OpenSSL is properly configured by running the following command:

openssl version

This command should output the version of OpenSSL installed on your system.

Step 2: Rebuild RSpamd with OpenSSL Support

RSpamd needs to be rebuilt with OpenSSL support to resolve the error. You’ll need to:

• Edit the RSpamd configuration file (rspamd.conf) to include OpenSSL support:

sudo nano /etc/rspamd/rspamd.conf

Add the following lines to the configuration file:

openssl {
  enabled = true;
  ca_bundle = "/path/to/ca_bundle.crt";
  key_file = "/path/to/ssl_key.pem";
  cert_file = "/path/to/ssl_cert.pem";
}

Replace the paths with the actual locations of your SSL/TLS certificate files.

• Rebuild RSpamd with OpenSSL support using the following command:

sudo rspamd -u

This command will rebuild RSpamd with OpenSSL support enabled.

Step 3: Verify RSpamd Configuration

Verify that RSpamd is properly configured by running the following command:

rspamd -t

This command will test RSpamd’s configuration and output any errors or warnings.

Step 4: Restart RSpamd Service

Finally, restart the RSpamd service to apply the changes:

sudo service rspamd restart

This command will restart the RSpamd service and reload the configuration.

Troubleshooting Common Issues

If you’re still experiencing issues after following the steps above, here are some common troubleshooting steps to try:

Check OpenSSL Version

Make sure you’re using a compatible version of OpenSSL. RSpamd requires OpenSSL 1.1.1 or higher. You can check your OpenSSL version using the following command:

openssl version

Verify RSpamd Configuration File

Double-check your RSpamd configuration file for errors or typos. A single mistake can cause the error to persist. Use a tool like rspamd -t to validate your configuration file.

Check RSpamd Logs

Consult RSpamd’s log files to identify any errors or warnings. You can find the log files in the /var/log/rspamd directory. Use a tool like grep to search for specific errors:

grep "EVP_" /var/log/rspamd/rspamd.log

This command will search for any errors related to EVP functions in the RSpamd log file.

Conclusion

In conclusion, the “RSpamd error: undefined reference to ‘EVP_*'” error can be frustrating, but it’s relatively easy to fix. By following the steps outlined in this article, you should be able to resolve the error and get RSpamd up and running smoothly. Remember to double-check your OpenSSL version, RSpamd configuration file, and log files to ensure everything is properly configured.

Troubleshooting Step	Description
Check OpenSSL Version	Verify that you’re using a compatible version of OpenSSL (1.1.1 or higher)
Verify RSpamd Configuration File	Double-check your RSpamd configuration file for errors or typos
Check RSpamd Logs	Consult RSpamd’s log files to identify any errors or warnings

By following these steps and troubleshooting common issues, you should be able to fix the “RSpamd error: undefined reference to ‘EVP_*'” error and ensure that your email server is running smoothly and securely.
