Linux development/minimal smtp and pop3 server

Question

I use python based as well as rails applications on ubuntu linux. We have functionalities like register, forgot password, reset password, email alerts etc features based on emails. Since now a days, we go on offline development, we want to run a local smtp & pop3 server to send and receive emails.

Emails shall be send via the our web application and we will use the email clients like thunderbird to receive emails(just to verify).

I have used jmailsrv (I have used 6 years ago, but could not locate exact package now), a java based simple email server. Are there any other light alternative for development work?

Answer 1

Why does it need to be a simple mail server?
Can't you just use something like postfix which is very easy for simple configurations
