Weird entries in SmarterMail ErrorLog
Problem reported by Jay Altemoos - September 18, 2017 at 8:30 AM
Looking over some error logs in SmarterMail I noticed something very odd. I am seeing the following in the log: (I masked our server address. Changed it to for the purpose of this post)
System.Exception: Null exception (likely a 404 or something else produced by IIS)
Application Error
Upon further investigation for several months this similar events like this appear in several logs. This almost looks like an attempt to inject a URL and redirect a user. I have scanned the server for infections and it's clean.
Has any one else seen similar issues like this in their logs?
