 # docker-mailserver
 
+[![Build Status](https://travis-ci.org/tomav/docker-mailserver.svg)](https://travis-ci.org/tomav/docker-mailserver)
+
 A fullstack but simple mail server (smtp, imap, antispam, antivirus...).  
 Only configuration files, no SQL database. Keep it simple and versioned.  
 Easy to deploy and upgrade.
