Confusing Error message issued when mime gateway is nonresponsive.

[curt@…]

When TRAC tries to send email notification of activity and the designated mime gateway is unresponsive, TRAC returns the a stack trace.

A more informative error message would be more helpful. A log of the SMTP dialog would be even better.

[Emmanuel Blot]

AFAICT, SMTP notification failures are now catched (in 0.9) and no Python trace is returned to the user. The error is nevertheless dumped to the logger.

The SMTP dialog with the SMTP server is handled by the Python smtp library, which makes it hard to retrieve.
