IMAP, sendmail and local delivery

[Tim Sandquist <tsandqui@yahoo.com>]

This if for all the mail gurus out there.  

How do you set up sendmail to work with Cyrus IMAP for delivering
mail but also deliver mail locally (i.e. to root).  

In my sendmail.mc I have 

MAILER(`local')
MAILER(`smtp')
MAILER(`cyrus')

among other things of course.  
I should probably give more info but if someone's done this alread it
probably won't matter much.

Any ideas?

Thanks,

Tim
