Dear, on our ispconfig 3.1.1.p1 master->slave configuration we have trouble to configure the relayhost of the slave server. Basically on the master server we put on the slave configuration: relayhost, relayuser and relaypassword from the GUI. When we save, on the salve that parameters are not gotten (they are always empty) so the plugin does not update postfix configuration. I have just found that exist an open issue: https://git.ispconfig.org/ispconfig/ispconfig3/issues/4381 Is that still not solved? Thank you.
The status of the issue is open, so it has probably not been verified and fixed yet. I've assigned it a bug label now.
Dear, we are going to update to 3.1.3 versione. Any chance that this version solve this bug? Thank you.
