No mail notifications sent after upgrade
After I'v upgraded Redmine from 1.3.1 to 2.3.0 it stopped sending mail notifications.
The configuration file seems OK (didn't change) but I didn't see anything from the associated email mailbox in /var/log/mail.log.
Also there are no more 'Sending email notification to: ...' lines in Redmine's log.
MY Ruby Version is:
ruby 1.9.3p429 (2013-05-15 revision 40747) [x86_64-linux]
Here is my configuration.yml
My Upgrade is stopped due to this issue.Please help me,its urgent
