mysqld running as "nobody" and php's mail func

[kyett]

I'm using the php mail func to send an email when a user "adds, deletes, or modify's" data in our database via a web interface. The emails are coming from user "NOBODY" which isn't making my firewall to happy!

Do anyone know what will break (if anything) if I change the directory structure of /opt/lampp/var/mysql from "NOBODY" to a "mydba"...add an entry in "my.cnf" under [mysqld] "user=mydba"?

I would simply try it...but this is a production server, so I can't just "play"!

Thanks for any info in advance!
