I think we wanted a second new config option PushFullSyslogMessage? we still need to keep this one as well, and mark it as deprecated

I can't do it, because RFC3164 message has lack of String() method. See implementation for RFC5424: https://github.com/leodido/go-syslog/blob/v4.1.0/rfc5424/builder.go#L9348-L9408

The issue that RFC3164 isn't well structured and quite flexible, and rebuild original message is quite a challenge.

Sorry to misslead you.

I think switching on the config.SyslogFormat would be cleaner

Here possible, but it is using in few more places, and it leads to == and need to export the contant name, or hardcoded strings...

So, I've decided to use trivial method which can be refactored.

Anyway, here only two RFC for Syslog, and I doubt that someone will make 3rd soon enough.
