Recipient unknown, when start workflow

[user21]

Hello!
When i strart workflow (parallel review), alfresco fail with message:

Failed message 1:
javax.mail.SendFailedException: Invalid Addresses;
  nested exception is:
        com.sun.mail.smtp.SMTPAddressFailedException: 550 <username_sl@list.ru>, Recipient unknown



I am use LDAP for authentication alfresco users. For other users workflow started successfully. Only for that user fail error.

My mail configure in alfresco-global.properties:
# Outbound Email Configuration
#————-
mail.host=xxx.xxx.xxx.xxx
mail.port=25
mail.username=user
mail.password=xxxxxx
mail.encoding=UTF-8
mail.from.default=user1@user1.ru
mail.smtp.auth=false

# Email Server properties
#————-
email.server.enabled=true
email.server.port=25
#email.server.domain=user1.ru
email.server.allowed.senders=.*

OS: CentOS 5.5
DB: Postgresql 8.4

How can i resolve that problem? Thank's!

Looks more like an email server config problem than an Alfresco config problem. Make sure that your email server is setup correctly and allows to the send emails to the recipients
your using.
