It does work on the server (BPM/CE7.11) in my office. (CE install in VMware along with mail Server, use same IP: 8.8.2.180)
But when I do the same thing on client's side, it just doesn't work out. (use the same VM instance, but in different Network environment)
I list the detail info. of settings and exception below:

Good day! I configured the notification but I stack with a problem.
There is an error in logs:
Could not send notifications due to Error: {...} nested exception is: com.sap.bpem.base.mail.MailException: com.sun.mail.smtp.SMTPSendFailedException: 550 authentication required
But I've entered the login and the password to the smtp. Where can I find a reason of the error?
Also I tried to configure notification service using the link http://help.sap.com/saphelp_nwce711/helpdata/EN/e4/32ff7865fa483dba3686160f5c6dd0/content.htm, but when I try to configure tcbpembase~ear service there is no edit button and the column "Modifiable" has no check. What it can be?
