Simple SMTP server for local development usage

Today I needed a local smtp server and I tried to connect firstly with my gmail account, but that’s not a good idea, because maybe you don’t want to commit your credentials and share them with your team.

Use Gmail SMTP Settings

If you want to use gmail server, with your credentials, here are the credentials:

Username: Your Gmail address (e.g.
Password: Your Gmail password
Port (TLS): 587
Port (SSL): 465
TLS/SSL required: true
