           Summary: Evolution cannot send email using encrypted SMTP server
           Product: Ubuntu
           Version: unspecified
          Platform: amd64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: evolution
        AssignedTo: seb128 at ubuntu.com

Error while performing operation.

RCPT TO <user at host.dom> failed: Command parameter not implemented

===

I get the above error message when attempting to send email.  My mail server is
running Postfix with TLS.  I am running Evolution 2.4.1 on
2.6.12-10-amd64-generic.  Within evolution, my preferences in the Account Editor
>> Sending Email indicate:

  Server Type: SMTP
  Server: mail.dunhackin.org
  [x] Server requires authentication
  Use Secure Connection: Whenever Possible
  Auth Type: DIGEST-MD5

Those exact same settings work on another machine I have, also running the same
version of Evolution on Ubuntu, but on an older Athlon machine.  They also work
on an i386 machine running Fedore Core 3, and a ThinkPad running Hoary.  This
mail server also works with Mozilla Thunderbird on both Linux and Windows.

I am currently up to date in terms of packages (apt-get update && apt-get
upgrade && apt-get dist-upgrade).

/etc/lsb-release says this:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=5.10
DISTRIB_CODENAME=breezy
DISTRIB_DESCRIPTION="Ubuntu (The Breezy Badger Release)"
