Assuming your email address change is as straight forward as you indicate
( ie, no names where truncated before but now they wont be etc ) then you
may find it much easier to leave the Cyrus mailboxes as is and go to your
sendmail configuration and add a rule to the cyrus delivery agent to remove
the underscore from the email address before passing off to lmtp.  This also
allows email addressed to the old style of email address to continue to be
delivered.

Depending on your sendmail skills, this may be and easy change or it may
take a few hours to figure out the details -- I fall into the later catagory
myself --
but it will probably take less time in the end.  You also are less likely to
do
damage to the cyrus system in the process.

Another options is to add aliases to your aliases database to map the new
address to the old ones.  This has the same benefits as the previous
suggestions but in the long run will be a nightmare to administer.

Cheers
Chris
