My only other thought is that if the connection in encrypted then its expecting a PLAIN password. Do i need to install the PLAIN mechnism in sendmail?
Would this expose my password if i set thunderbird to plain?
Would that be safe configuration?
Basically the way i read the error, it says the client does nothing
and sendmail just waits. I have set thunderbird to "starttls" and
"encrypted" password for the outbound emails.

250-AUTH DIGEST-MD5 CRAM-MD5
I guess yes. I have
TRUST_AUTH_MECH(`LOGIN PLAIN')dnl

It is currently not enabled, check confAUTH_MECHANISMS in sendmail.mc.
If you use port 587, STARTTLS is right. If you use 465
(DAEMONPORT_Options s-flag needed!), you need to use TLS (not STARTTLS).
If you require authentication (I recommend using that instead of
whitelisting IP addresses), you need to tell TB the auth details and configure it so it actually logs in. Check you /var/log/auth.log for
the login (if using system accounts (UNIX PAM etc.)) and your sendmail
log. You can also disable STARTTLS/TLS to see the content of the
traffic to check if the correct SMTP commands are issued by TB.

Thanks guys for all the responses. I added PLAIN to
confAUTH_MECHANISMS in sendmail.mc recompiled and restared, and that
did the trick! I am able to send email from ThunderBird.
I wanted to follow up about the ports though. I am running STARTTLS
on port 25. Is that a problem?
I want to make sure my PLAIN password is safe I think I am being
protected by STARTTLS. I see this message in the logs when i send
from ThunderBird.
