Being a System Administrator as well as a Web Developer I run into issues with the Mail protocol SMTP.
Things hang or people want their email better formatted. Or simply test out you spam messages you are going to blast before you well blast them.
Of course you run into issues like is my ports open correctly, is the SMTP server setup to block relaying? Has my domain been blacklisted from spamming?
These kind of questions are important. While I can’t fix the blacklisting domain issue the rest is well my night job.
However during the day I develop lots and lots of web code and sometimes and most often these applications need a way to contact people via email, txt and so forth.
Being behind a great firewall and sending test email can be a long and drawn out process. I found a great application to do the SMTP testing for you inside you own localhost(127.0.0.1) Yes that is my localhost ip if you would like to “hack me” go ahead Ill wait.(if you don’t already know that is the IP of your pc).
This little app allows you to send SMTP messages without sending them anywhere.
Paper Cut is my favorite application for development. It allows me to debug the SMTP messages without sending them to anyone.
