Looks like a problem with Cox that has not made its way down to the tech
support. See this almost identical post in OE General today. I would call
Cox back and ask to speak to a Tier 2 tech and cite this other persons
issue.

In Outlook Express 6.0 wife attempted to send a Group email and which was
returned as undeliverable due to the following error message:

The message could not be sent because its size exceeded the server's
limit.
You can use the option, located in Tools | Accounts | Properties |
Advanced,
to break messages into smaller parts. Subject 'Hello', Account:
'pop.west.cox.net', Server: 'smtp.west.cox.net', Protocol: SMTP, Server
Response: '552 5.2.0 NmhK1b00L3hcpaG04mhKj9 This message was
undeliverable.
This message has been found to be a potential spam message, and has
therefore
been blocked. Please visit http://coxagainstspam.cox.net for more
information.', Port: 25, Secure(SSL): No, Server Error: 552, Error Number:
0x800CCC6D

This was attempted to a Group of 83 recipients, and the message size is
5kb.
So far, the best Cox could tell me is to check that the 'syntax' of all
recipients in the Group is correct; they are.
Thanks in advance for any and all help.
