Describe your issue
The diagnosis screen shows an issue with reverse DNS for IPv6 and email. I would like to disable IPv6 for email as suggested in the error message.
The suggested command is yunohost settings set smtp.allow_ipv6 -v off
but that doesn’t work and gives this error message “Error: You can’t set a single value on an entire config section”.
I found that the correct command is yunohost settings set email.smtp.smtp_allow_ipv6 -v off
abd I’m sharing here in case it’s useful for other users.
