I have linux mail server running courier imap/pop3
This is strange, it just started happening today. This server has been running fine for a couple of years now.
What is happening is the authentication is rejected, all we have to do is click ok and it works fine, without changing the username or password. And it doesnt do it all the time. And there is nothing in the logs about any failed authentications. Any body have any ideas on what might be happening and any solutions. Google didnt really help.
