  • E-MailRelay — SMTP proxy and store-and-forward MTA – E-MailRelay is a simple SMTP proxy and store-and-forward message transfer agent (MTA). When running as a proxy all e-mail messages can be passed through a user-defined program, such as a spam filter, which can drop, re-address or edit messages as they pass through. When running as a store-and-forward MTA incoming messages are stored in a local spool directory, and then forwarded to the next SMTP server on request.

    Because of its functional simplicity E-MailRelay is easy to configure, often only requiring the address of the target SMTP server to be put on the command line.

    E-MailRelay can also run as a POP3 server. Messages received over SMTP can be automatically dropped into several independent POP3 mailboxes.

    C++ source code is available for Linux, FreeBSD, MacOS X etc, and Windows. Distribution is under the GNU General Public License V3.

  • Monitor Your Website in Real-Time with Apachetop – How-To Geek – As a webmaster, I’ve often wanted to be able to see real-time hits as they arrive. Sure, Google Analytics is a wonderful package for looking at trends over time, but there’s a delay of a few hours there, and you really can’t see data like requests per second or total bytes.

    This is where the apachetop utility comes in. It’s a very simple command line utility that you can use to monitor traffic real-time. It accomplishes this by parsing the apache logfiles and displaying meaningful output to the screen.
