Perplexity

Scripted provisioning with Claude Code

Stop logging into web panels to create email accounts. This integration lets you manage your entire mail infrastructure straight from the command line. You pipe in a list of new hires, and your agent handles the rest. The agent loops through your list and fires off `create_mail_user` for each person. If they need to receive emails from a legacy address, it immediately runs `create_or_update_alias`. You get a fully provisioned team in seconds.

Infrastructure health checks

Mail servers require constant babysitting. DNS records drift, SSL certificates expire, and spam blacklists happen. You need real-time visibility without leaving your SSH session. You can trigger `get_system_status` directly through your agent. It pulls the raw diagnostic JSON, parses the output, and alerts you to any failing services. Tie this into a cron job to catch issues early.

Automated teardown and cleanup

Offboarding users manually is a security risk. When someone leaves, you need their access revoked and their aliases wiped immediately. The agent pulls the active roster using `list_mail_users`. Once you confirm the target, it executes `delete_mail_user` and cleans up any orphaned routing rules with `delete_mail_alias`.
