[Evolution] Postfix TLS and Evolution

[Franck Routier <franck routier axege com>]

Hi,

I have set up a mail account and wish to send outgoing mails via a TLS 
secured Postfix server.

My setup for outgoing mail server in Evolution is :

Server type :     SMTP
Server :             myserver.com:20025
Server requires authentication : yes
Use secure connection : always
Authentication type : Digest-MD5
User name : myname myaddress com
Remember password : yes

nb : smtpd is listening for tls connections on port 20025.

When I send a mail from Evolution, on the smtp server, Postfix log says :

Dec 12 17:22:41 localhost postfix/smtpd[32521]: connect from 
xx.xx.xx-xx.rev.gaoland.net[xx.xx.xx.xx]

and that's it. On the client, evolution's 'send/receive mail' dialog box 
stays open forever.

I think that the TLS connection is not started.

If I send a mail with another client type (mozilla), I get on Postfix log :

Dec 12 17:22:41 localhost postfix/smtpd[32521]: connect from 
xx.xx.xx-xx.rev.gaoland.net[xx.xx.xx.xx]
Dec 12 17:22:41 localhost postfix/smtpd[32521]: setting up TLS 
connection from xx.xx.xx-xx.rev.gaoland.net[xx.xx.xx.xx]
[lot of low level info related to ssl and certificates...]

and message is sent.

Does anyone have a tip to help me sort this out ?
Thanks in advance,

Franck
