Ok, so the message does not get delivered, but if you are getting 500 SMTP headers a day, plus a message getting sent to the machine that sent it, wouldn't that add up to a lot of bandwidth that is wasted?
Also, if you send a message to [EMAIL PROTECTED] and there is no idiot there and then the postmaster sends a message to the person that sent it, but, the person that sent it is also an invalid e-mail, wouldn't the system keep retrying to send it, based on your configuration? I turn the nobody account on for small domains, with one or two addresses, but on a large one, like Planet Hollywood, I leave it off.

No, the message should never be received by your server; the address should be rejected during the SMTP envelope (which consumes its small share of resources, but nothing like receiving a message entirely). Are you using IMail's 'nobody' alias (a catchall account)? If not, IMail will not accept mail to unknown users at local domains. There is likely a configuration error if 'tis not so at your site. > So, if I get spam from 212.212.212.212, will all mail from that > address in the future be blocked?

Whether you maintain private IP blacklists is simply a matter of the personpower dedicated to messaging systems. -Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] ------------------------------------ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
