User constantly loggin into mail?
 
Hey everyone,

I am just peeking around in my mail log and noticed that I have one of my users that is almost always logging in and out of imap. Here is a portion of the log, Should I be worried?

Code:

..The log goes back quite a ways.

That user probably configured his email client to check for mails every minute. If this causes a problem for your server (load-wise), you should contact that user and ask him to stop this.

I suppose that he could have just left the webmail client open all day, it was just a little disturbing to see, I didn't know if something happened.

Thanks Falko!
