Paired Custom Tags

Can anyone point me at a good resource for learning about writing a Paired custom tag?  I'm having a little trouble with the one I started on yesterday. Basically what we're trying to do is "overload" the cfmail tag so that we can make it work differently on different servers. I have created a tag with a start and stop which I think is pretty good. When you call it it does generate an email like you'd expect, but the content of the mail tag also displays on the screen which is a little less than ideal.  If anyone's got some pointers on how to get this working right I'd appreciate it.  I think it will work out pretty nice once I get over this learning hump.
