Mail configuration fails, server sends "250 STARTTLS"

[troy kay]

Hey folks, 

I'm trying to configure Crowd 4.1 to send mail using our internal SMTP servers, and I'm hitting a bit of a bump that causes it to fail.  

The mail server transcript: 

250 STARTTLS

STARTTLS

220 Go ahead with TLS

I don't see anything in the SMTP server section having to do with TLS. 

Anyone have a pointer? 

Thanks
