Comment 5 for bug 1215882

Steps to reproduce:

When I send a mail using an incorrect smtp server (e.g. I have stmp.telenet.be configured but I'm at a customer whose ISP only accepts relay.skynet.be), and the server sends an error message instead of just timing out,

Actual results:

I get an error message (as I used to get), but instead of keeping the composer window open, the composer window is closed and the mail (which has not been sent succesfully) ends up in my SentMail.

Expected results:

Before the latest update, I would get an error message but the composer window would remain open so:
- I would know that sending failed
- I could try again with the correct smtp server
