Email Service With Receiving and Sending Problems

Hello friends, how are you?
Can Someone Help, My CWP Email Server Has Problems, As Pictures Below, Every Time I Need It For The Webmail Service To Get Back Working, It Works For Awhile, Then Stops, Sometimes The Emails Don't Arrive In Webmail And Sometimes They Don't Send, An Intermittent Service, How To Permanently Solve It?



Obrigado! Thanks

Seeing as it's intermittent, I'm going to go out on a limb and say you have issues with either space, or IOstreams.  I say this because of the "Failed to write" error.  Check if user limits are set on the drive.
