Changing Parameters via CLI

[DaveDischord]

So I screwed something up and changed some webmail settings under Modoboa>Parameters>Webmail (IMAP port I believe) and now I get a 404 when trying to open the web interface. mail.domain.tld returns "404 Not Found | nginx/1.14.0 (Ubuntu)". I was hoping to remedy this in CLI, but I have no idea where to find and fix these settings. Any idea/other suggestions? Thanks
