Does anyone have a grok for Barracuda SPAM filter?

I'm wanting to send my Barracuda SPAM filter logs into ELK and wanted to know if anyone had already worked of a grok and filter for it?

Barracuda has a great page that explains what the fields mean, but I'm still new to writing Logstash input filters.

Thanks!

I'm also trying to filter Barracuda syslog mail, but without success until now
