bug#9416: 24.0.50; Emacs hanging when attempting to send email

[nyc4bos]

Hi,

When attemping to send email with the latest Windows
version of Emacs, it hangs after printing the
status message:

220 2.0.0 Ready to start TLS

Here is the "*trace of SMTP session" buffer:

220-mtaout-da04.r1000.mx.aol.com ESMTP MUA/Third Party Client Interface
EHLO HOSTNAME
250-mtaout-da04.r1000.mx.aol.com
250-PIPELINING
250-SIZE 36700160
250-ETRN
250-STARTTLS
250-AUTH PLAIN LOGIN XAOL-UAS-MB
250-AUTH=PLAIN LOGIN XAOL-UAS-MB
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
STARTTLS
220 2.0.0 Ready to start TLS
QUIT

I can only then press ^G which then quits.

How can I debug this?

Thanks.
