Yes but:
1) newer cyrus releases can use "hashing" more complicated than "first letter"
2) newer cyrus releases support virtual domains with virtual domain name
included in the mailbox path
3) I prefer to keep all cyrus data and mailboxes available *ONLY* to cyrus
user to improve security and AFAIR exim does some verifications as exim user

BTW if you want to use cyrus with virtual domains as local transport then
* only "non virtual cyrus domains" should be converted to "default cyrus
domain" (or stripped)
* you must solve subtle problems with "domanized" and "local part only" aliases
It can be solved by "rewriting" recipient's domain to the default cyrus domain
before selecting callout ready cyrus_ltcp transport as "local transport" and
handling virtual domains earlier.
