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):
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
Evolution cannot store the mail in sent folder.
Mail stored in imap folder using TLS.
It is also a security risk, because Evolution sends plaintext password though it is configured not to do so.
Thanks for a bug report. I moved this upstream as , because this doesn't seem to be fedora-specific issue. Please see  for any further updates. If possible, please CC yourself there, in case upstream developers will have additional questions.
