I can't change the email config on ISPConfig 3.1.6. Actually, I didn't change any information on the configuration form. I can't even change to another tab.
There is a bug report for this: https://git.ispconfig.org/ispconfig/ispconfig3/issues/4462 Also, other forum posts. Please refer to search option in the future https://www.howtoforge.com/communit...erver-config-mail-settings.74419/#post-353592
