[Users] [maybe-BUG] SSL-Handling

[moonkid at posteo.org]

Depending on my experience with mailprovider posteo.de and another
users experience with t-online I suggest that Claws-Mail handle
SSL-connections a little bit different comparing to other mail-clients
(outlook, thunderbird, apple-mail, ...).

Posteo and T-Online switched of there SSLv3 (for external
clients; POP3, SMTP, maybe IMAP) because of the Poodle-Attack.

Claws SSL-connections failed. In the account settings was SSL activated
but STARTTLS was NOT. After activating STARTTLS everything worked fine.

I don't know enough about the SSL and the other involved
shakehanding-protocals while establishing a SSL-connection.

But Posteo sad to me that tests with other mail-clients and deactivated
STARTTLS made no problems.

So this indicates for me that Claws make something different comparing
to other clients when establishing a SSL connection without STARTTLS.

So what can you tell about it? Maybe it is a bug?
