Tailing logs

[DAve]

I would love to have a way to tail a log, like piping to grep, except I 
see every line and the lines I would normally grep for are highlighted. 
That would be cool. Anyone know of a bash command or tool that will do this?

Side note, I am tailing sendmail after changes to my outbound queue 
runners. I want to highlight my sm-mta-out lines but still see all lines.
