Thank you for using Nodemailer for your email sending needs! While Nodemailer itself is mostly meant to be a SMTP client there are other related projects in the Nodemailer project as well.

For example:
> IMAP API ( https://imapapi.com ) is a server application to easily access IMAP accounts via REST API
> NodemailerApp ( https://nodemailer.com/app/ ) is a cross platform GUI app to debug emails
