Email won't send after upgrading to Bamboo 5.10.3

We recently upgraded from Bamboo 5.9.1 to 5.10.3.  Since then we have not received any email notifications.  I checked the catalina.out file and found:

2016-04-11 11:48:24,095 ERROR [http-nio-8085-exec-23] [EmailService] Failed to send email

The Stash server which is on the same host is still successfully sending emails.

I have tried No TSL, TSL, no password, password, etc. all to no avail.

In our case we had cleared the username and password used to connect to the SMTP server so that we would use anonymous SMTP connections.  But it seems that to get this to take effect, Bamboo itself has to be restarted.

Just found that atlassian-bamboo-5.9.1/atlassian-bamboo/WEB-INF/lib/mail-1.4.1.jar exists but atlassian-bamboo-5.10.3/atlassian-bamboo/WEB-INF/lib/mail-1.4.1.jar does not (nor any other version of the same).

Tried copying it in pace - but to no avail.

Presence of a JAR is not an issue here. Bamboo-5.10.3 uses more recent version of javax.mail package and JAR file is now located in WEB-INF/lib/javax.mail-1.5.2.jar

Is there any solution to it? We liked to have email notifications

@Boris Alyurov, please create support request at 

JavaMail was updated in Bamboo 5.10.3 from 2.4.1 to 2.5.12 and some clients had issues with Microsoft Exchange server access. Our support engineers will help you

This is resolved now. We change the email configuration to use TLS. It would have been great if this gotcha issue was documented in the release note.
