Solaris+cyrus_imap+sendmail

[Antonio Xu]

Hello, All
       I'm a volunteer work for mozilla's mailnews, now I have set up a 
cyrus imap server for my testing, but I meet a problem of how to 
configure the cyrus's Imap server and make it can work with sendmail. I 
set up the server on solaris, so I meet some problme. I use solaris8 and 
cyrus-imapd-2.1.9. I need your help due to I could not find a correct 
document about how to configure sendmail and make it work with 
cyrus-imap on solaris. I only know I must edit sendmail.mc file and 
createsendmail.cf file with it. But I don't know how to hold my old 
setting like domain name, my sendmail.mc file like that

#    This sample mc file is for a site that uses the Cyrus IMAP server
#    exclusively for local mail. This requires Sendmail 8.10 or later.

VERSIONID(`cyrus v2 sample configuartion')

OSTYPE(`solaris8')
define(`confBIND_OPTS',`-DNSRCH -DEFNAMES')
define(`confTO_IDENT',`0')

dnl setting cyrus as the trusted user will make it easier to pass
dnl Sendmail's safefile checks.  however, it means that someone with the
dnl "cyrus" password could easily become root.
dnl define(`confTRUSTED_USER', `cyrus')

LOCAL_RULE_0
Rbb + $+ < @ $=w . >    $#cyrus $: + $1

I  used the above file for creating a  new sendmail.cf file,then restart 
sendmail, but now I can not receive or send  email with the new sendmail.cf
I need some advices about how to configure sendmail correctly setp by setp.
Thank you
