Hi, Last week I installed 3.1.14p1 on two servers running Debian Buster. Server 1 runs Web, DNS, File and DB. Server 2 runs Mail and DNS (configured as mirror of Server 1). Everything was running fine until today I noticed the security update and run "ispconfig_update.sh" on both servers and upgraded them to 3.1.14p2. After that I can no longer add mail domains. The "Add new domain" form does not list the mail server in the "Server" field as it used to, just "No matches found". In the System tab I can still see both servers and mail is active in Server 2. I tried removing the mail service from Server 2 and adding it again but the problem remains. Anyone knows how to fix this? Thanks!
