Title: Message

In services go to SMTP and clear the max invalid recipients per session for dictionary attacks; that should turn it off.  (Note, you'll need to restart smtpd after changing).   Tripp   ----- Original Message ----- From: Matrosity Hosting To: IMail_Forum@list.ipswitch.com Sent: Tuesday, December 06, 2005 5:03 PM Subject: Re: [IMail Forum] smtp stuck at 21% no, this is new. It bounces up and down but doesn't seem to go below 21%. The only settings we've changed have been those of the dictionary attacks. I haven't seen a checkbox to turn off dictionary attacks?

Yes. Nothing that seems out of the ordinary. We're using spamhaus, china and spamcop. Dictionary is set to block for 24 hours. Note that a recycle of the smtp service sets it back to 0% and normal operation.
