sendmail "verify=FAIL" messages in mail.log

[talz13]

I have logcheck running, and sending notifications to NotifyMyAndroid on my phone. I'm seeing the following messages come up whenever logcheck sends a message. Any clue why this is happening? It seemed to start after I rebooted the Ubuntu server.

Unless you have purchased an SSL certificate from a third-party provider, you will get this error. It simply means that the certficate included with the server cannot be verified, since it is "self-signed" and not signed by a provider like Thawte or Verisign. The transfer will still be encrypted, but the identity of the server cannot be verified.

Thanks, I've added this to logcheck's ignore filters now.
