Hi Dominik,
I reviewed the accepted answer on the link that you shared.
Our application is a console application that was compiled against .net
framework 4. We are using the framework 4.0 version of the log4net dll.
Windows server 2003 does not support .net framework 4.5.
ClaimsIdentity Class was introduced in framework 4.5.
(https://msdn.microsoft.com/en-us/library/system.security.claims.claimsidentity.aspx).
Why is the log4net dll referencing this class?
Thanks and Regards
Mohkam Singh

We recently updated our application to use Log4Net v2.0.8, with the same
configuration for SmptAppender . After this update, we stopped receiving
emails. On enabling the internal log4Net logging, the below error was logged.

If we revert back to Log4Net v1.2.13.0, we start receiving emails as expected.
Please advise how can we resolve the issue with version 2.0.8.
