sendmail configuration to relay to hosted exchange server via SSL

Hi,

I've been trying to tackle a setup for the past few days with my sendmail server.  I need to relay emails to our exchange server for proper delivery to my users.  Our hosted server allows Relay using SSL.  I've configured a user on the exchange side to allow relay which would be used by my sendmail config.

Currently the issue that i'm having is that though i've generated the needed certs I see through the maillog that sendmail is not finding them.

I've been reading a significant amount of posts on configuring sendmail to use ssl to relay but at this point i'm pretty confused as to what I may be missing.

I'm using Centos 5 / sendmail 8.13.8

The config parameters i've added to the .mc file are

define(`confCACERT_PATH', `/etc/mail/certs')dnl
define(`confCACERT', `/etc/mail/certs/ca.crt')dnl
define(`confSERVER_CERT', `/etc/mail/certs/sendmail.crt')dnl
define(`confSERVER_KEY', `/etc/mail/certs/sendmail.key')dnl
define(`confTLS_SRV_OPTIONS', `V')

DAEMON_OPTIONS(`Name=smtps,Port=smtps, Modifiers=s')
DAEMON_OPTIONS(`Name=smtp,Port=smtp')

define(`SMART_HOST', `smtpx1.my.net') (relay hostname)

I've also added the authenticated user account needed to talk to exchange server under the authinfo file.

AuthInfo:smtp1.my.net "U:ti@hostname.com" "P:Passw@rd" "M:PLAIN"
AuthInfo: "U:ti@hostname.com" "P:Passw@rd1" "M:PLAIN"

Any ideas or suggestions i should be following on this?

Thanks!
