ProxSMTP is a flexible tool that allows you to reject, change or log email based on arbitrary critera. It accepts SMTP connections and forwards the SMTP commands and responses to another SMTP server. You need to be able to write the filtering scripts that integrate it with your particular needs. This port is an adapted version of security/clamsmtp one, as the two programs are from the same author and quite similar in functionality.
State Changed From-To: open->closed New port added, thank you!
