This container is free to use and has no license limitations.\n\n\nThis optimized image is functionally equivalent to [Platform One Postfix IronBank][source-image-repo-link] image but more secure with a significantly smaller software attack surface.\n\n[![Vulnerabilities by severity][vulns-chart-svg]][vulns-chart-link]\n\n[![Original vs. this image][savings-svg]][savings-link]\n\n[![View Report][full-report-svg]][full-report-link]\n\n

\n\n\nEvery day, RapidFort automatically optimizes and hardens a growing bank of Docker Hub’s most important container images. \n\nCheck out our [entire library of secured container images.](https://hub.docker.com/u/rapidfort)\n
\n\n[Get the full report here or click on the image below][rf-view-report-link]\n\n## What is Postfix IronBank?\n\n> Postfix is Wietse Venema's mail server that started life at IBM research as an alternative to the widely-used Sendmail program\n\n\n[Overview of Postfix IronBank](https://www.postfix.org/)\n\nTrademarks: This software listing is packaged by RapidFort. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.\n\n\n## How do I use this hardened Postfix IronBank image?\n\n\n\nThe runtime instructions for this hardened container image are the same as the official release. Follow the instructions provided with the [Platform One Postfix IronBank][source-image-repo-link].\n\n\n[![View Detailed Instructions](https://raw.githubusercontent.com/rapidfort/community-images/main/contrib/view_details.svg)](https://repo1.dso.mil/dsop/opensource/postfix/-/blob/development/README.md)\n\n

Removing unnecessary software components is a critical practice to protect your infrastructure from attacks and limiting the blast radius of any attacks.\n\nThis image is a hardened version of the official [Platform One Postfix IronBank][source-image-repo-link] image on Docker Hub.\n\nVulnerability reports for RapidFort's hardened images are updated daily to include newly discovered vulnerabilities and fixes.\n\n\n[![View on GitHub](https://raw.githubusercontent.com/rapidfort/community-images/main/contrib/view_github.svg)](https://github.com/rapidfort/community-images/tree/main/community_images/postfix/ironbank)\n
