xstress is a small yet powerful tool to stress test SMTP mail servers. xstress creates multiple threads and sends mail messages with varying subjects, "to" addresses, and body texts. Mail attachments are supported. All the parameters are highly configurable. For example, you can configure the number of threads xstress creates, SMTP timeout, attachment files, "to" address, "from" address, etc. License: GNU General Public License v2 Changes:
