I am sending an e-mail message to 40 clients with a large file as an attachment. When I send the message with the attachment I get a message back telling me- Server response: 554 home.com no longer exists and the error number 0x800ccc6f.
Please help me.

Thank you.

Home.com does not exist anymore. Take a look at your distribution list and get a new address for that client.

CAUSE
The senders' SMTP e-mail address that is configured in Outlook and Outlook Express (POP3 or IMAP client) does not match an address in the Exchange directory and cannot be validated by the Internet Mail Service.

RESOLUTION
This resolution assumes the Exchange Administrator wants to retain the anti-spoofing configuration on the Internet Mail Service.

In Outlook Express, ensure the e-mail address entry (from the Tools menu, click Accounts , click the Mail tab, select the User name , click Properties , and then click the General tab) is the same SMTP e-mail address for the Exchange user located in the Exchange directory (under the Exchange user properties, E-mail addresses tab, SMTP address).

Thank You,
