 ## Overview
 `add_whitelists.sh` is a universal script to add domains and IP addresses to Postfix and Postgrey whitelists. It supports **single-entry** and **bulk-from-file** modes. The script **auto-creates** missing files/directories, makes **timestamped backups** before changes, **ignores** blank lines and `#` comments, **deduplicates** entries, and **restarts** Postfix/Postgrey only when changes are made. At the end it prints how many entries were added and a list of what was actually added.
 
 ### Usage
 
 **Single entry**
+
     sudo ./add_whitelists.sh example.com
     # or
     sudo ./add_whitelists.sh 203.0.113.7
 
+

     example.com
     mail.example.org
     192.168.1.10
+
