Уведомления отслеживания (smtp) и Postfix

У меня два отдельных сервера ubuntu 12.04.

1. Запускает Trac (домашний сервер / Dyndns)
2. Запускает postfix (VPS / staticIP)

Я настроил trac для использования TLS и подключения к серверу postfix.

Конфигурация Trac:

admit_domains =
always_notify_owner = true
always_notify_reporter = true
always_notify_updater = true
ambiguous_char_width = single
email_sender = SmtpEmailSender
ignore_domains =
mime_encoding = base64
sendmail_path = sendmail
smtp_always_bcc =
smtp_always_cc = sandro@weare.de.com
smtp_default_domain =
smtp_enabled = true
smtp_from = trac@weare.de.com
smtp_from_name = Trac
smtp_password = randompassstring==
smtp_port = 587
smtp_replyto = trac@weare.de.com
smtp_server = vps.idev.ge
smtp_subject_prefix = __default__
smtp_user = trac@weare.de.com
ticket_subject_template = $prefix #$ticket.id: $summary
use_public_cc = false
use_short_addr = false
use_tls = true

Когда я пытаюсь отправить уведомление, Trac говорит:

ERROR: Failure sending notification on change to ticket #1: SMTPAuthenticationError: (535, '5.7.8 Error: authentication failed: authentication failure')

Постфикс говорит:

Anonymous TLS connection established from unknown[78.139.167.29]: TLSv1.1 with cipher ECDHE-RSA-AES256-SHA (256/256 bits)
warning: SASL authentication failure: incorrect digest response
