Description of problem:

I use a imapx account with TLS security.
When I send a message, I get this error :
[CLIENTBUG] Plaintext authentication disallowed on non-secure (SSL-TLS) connections.
My mail server is configured to refuse plaintext login on non secure connection. 
Evolution is correctly configured to use secure connection (I tried with both TLS and SSL) settings. So after sending a message it seems to ignore this settings when trying to move the message to the sent folder.


Version-Release number of selected component (if applicable):
evolution-3.0.0-1.fc15

How reproducible:


Steps to Reproduce:
1. Use mail server with plaintext login refused on non secure connection
2. Configure imapx account with TLS connection
3. Configure the account to store sent mail on imap server
4. Send mail
  
Actual results:

Evolution cannot store the mail in sent folder.

Expected results:

Mail stored in imap folder using TLS.

Additional info:

It is also a security risk, because Evolution sends plaintext password though it is configured not to do so.
