Development Tool of the Day: smtp4dev

I wanted to take a few minutes to talk up a cool little tool that I started using a few weeks ago and have since come to rely upon.

smtp4dev (http://smtp4dev.codeplex.com/) is a dummy smtp server that, instead of sending email messages, stores them in a list for easy viewing and inspection.  Before I started using this tool, any time I wanted to test email sending for an application I had to, first of all, sanitize all of my data to make sure I didn't accidentally send messages to people that shouldn't get them, and then make sure any messages I needed to inspect were sent to my email account.  I would have to wait for messages to arrive in my inbox and deal with all of the test messages getting mixed up with my regular mail.  It was a big hassle, in other words.

An added benefit for me is that, since I access my regular mail through Gmail, I am able to easily open up the messages in Windows Live Mail (also a free download) which seems to replicate the way the email displays in Outlook.  For highly styled messages this is very important, since Outlook is a very popular client that has quite a few display quirks.

Testimonials

  • I love working with Modern Signal! Their CMS is very easy to use and they are incredibly responsive to questions or challenges I bring them.

    - NALP

  • Modern Signal worked with us to understand our needs and figure out what solution would work best for us. Our Lighthouse CMS is perfectly suited to our website goals. When we later needed to modify the CMS, they again took the time to understand exactly what was  needed and then built that functionality rather than delivering a cookie cutter solution.
