Linux Softwares to Email Forwarding

Postfix is a widely used and highly regarded open-source mail transfer agent (MTA) designed to be a significantly more secure and robust alternative to Sendmail. It handles the routing and delivery of email, acting as the central hub for your organization's or system's email flow.

Spamgourmet provides disposable email addresses that are automatically created upon first use, forward messages to your real inbox, and then expire after a set number of forwards or a defined time period, significantly reducing spam.
