Hi emawata,
Checking your configuration snippet it seems that `d_mailwarn` and `d_mailinfo` are not connected to a logpath, which is why syslog-ng doesn't write into them. If you wish to use them create a `log{};` block, which fetches data from source and writes it into
`destination(d_mailwarn);` or `destination(d_mailinfo);`
Hope it helped,
