Issue
Certain companies and SMTP mail servers require specific security protocols in order to accept messages. The requirement of Transport Layer Security (TLS) or Secure Sockets Layer (SSL) protocols can cause errors when the Vista alarm email notifications fail to send.
Product Line
TAC Vista
Environment
- Vista Workstation
- Xenta Server
- Alarm Emails
Cause
Xenta server email notification does not have the option to use TLS or SSL security protocols
TAC Vista email notification does not have the option to use TLS or SSL security protocols in versions prior to the 5.1.9 hotfix 17 build.
Resolution
The latest hotfix versions for Vista can be downloaded off of The Exchange Download Center. In order to obtain the SSL and TLS support for smtp server communication, Vista 5.1.9 hotfix 17 or later must be used.
Prior to Vista 5.1.9 Hotfix 17 - Vista did not support Transport Layer Security (TLS) or Secure Sockets Layer (SSL) for sending alarm email notifications. A workaround for this issue is to set up an SMTP server on the local machine or network that the Vista or Xenta server resides on. Then the email notification can be encrypted with TLS or SSL protocol before being sent on.
