Hi again,
we updated our Continua installation today and now we no longer receive notification mails for our builds.
The following errors schows up in the event log:
Importance: Warning
Date: Tuesday, May 12, 2015
Time: 2:00:00 PM
Message:
Notifications
Failed to send email notification after 4 attempts, discarding message:

I have also attached a screenshot of our current e mail configuration. The same settings worked with the previous Continua build. I have also tried pretty much all other combinations for these settings and none of them were successful.

Since the forum software seems to have delete the ‘MAIL FROM’ and ‘RCPT TO’ parts of the original message I have added another screenshot.

Hi Christoph,
Thanks for reporting this. Can you try the following build:
- [Continua CI Installer (64-bit) v1.6.0.188](http://downloads.finalbuilder.com/downloads/continua/1.6/ContinuaCI.Server.Setup_x64_1.6.0.188.exe)
- [Continua CI Installer (32-bit) v1.6.0.188](http://downloads.finalbuilder.com/downloads/continua/1.6/ContinuaCI.Server.Setup_1.6.0.188.exe)
- [Continua CI Agent Installer (64-bit) v1.6.0.188](http://downloads.finalbuilder.com/downloads/continua/1.6/ContinuaCI.Agent.Setup_x64_1.6.0.188.exe)

Unfortunately the new build does not seem to have helped. Except now there are no more event log entries for the mails.
When validating the mail settings we still get the same error message as originally reported.

After a while we did get the event log entries. I have attached the log file.[\_\_34733\_\_0\_\_event-736b5558.zip](https://www.finalbuilder.com/forums/uploads/default/original/2X/f/f108440a1a153962ee271a2c7989d1c3b8ee6173.zip) (1009 B)

Apologies, this is a bit trial and error as we have not yet managed to get an Exchange server installed to test this properly . Please try the following build:
- [Continua CI Installer (64-bit) v1.6.0.189](http://downloads.finalbuilder.com/downloads/continua/1.6/ContinuaCI.Server.Setup_x64_1.6.0.189.exe)
- [Continua CI Installer (32-bit) v1.6.0.189](http://downloads.finalbuilder.com/downloads/continua/1.6/ContinuaCI.Server.Setup_1.6.0.189.exe)
- [Continua CI Agent Installer (64-bit) v1.6.0.189](http://downloads.finalbuilder.com/downloads/continua/1.6/ContinuaCI.Agent.Setup_x64_1.6.0.189.exe)

That build works like a charm. Thanks the fast work.
