Hello, Debian 4.9.168-1+deb9u4 (2019-07-19) x86_64 ISPConfig Version: 3.1.14p2 single Nginx How to allow custom rules to clients in Email Mailbox? Client Admin
Okay. It is therefore necessary to implement Managesieve in Roundcube. I just installed ISPConfig on a new server. Managesieve forbids putting more than 55 custom rules in a filter. But on another server also with ISPConfig, there are many more rules. I do not remember what to do to allow this. How to do?
