I have recently started having an issue with mailman I have never used it but i have it installed. lately i have started receiving an e-mail at 8am every morning saying there's something needing my attention. It directs me into a link that uses HTTP but i assume due to my mgmt interface being redirected to HTTPS it wont let me login - the error message is error 500 internal server error. If i change the link manually on the browser to HTTPS i then get a wrong (and expired) self signed certificate error. I am using a public signed certificate with my domain name for the management page without issues except for this. Could anyone give me a hint on where to look for either how to allow mailman to send out https links and having the correct cert linked to it, or allowing it to use HTTP. I am using Centos 7.4, and ISPConfig 3.1.7p. i don't really use mailman for any domain, but i would at least like to remove this e-mail warning every day.
