Outook error, " 550 Error: Message content rejected" when sending to ANY email
Posted on 2007-04-09
Please read this carefully before replying. Other replies to similar problems have grossly missed the point of the question.
This is a sudden problem, no known changes to my system or Outlook settings. Using WindowsXP and MS Outlook 2003 to send email via POP3, its been working fine for years. Suddenly 90% of the emails I try to send get the following error message
550 Error: Message content rejected
from the "System Adminsitrator"
Key points missing in the other answers:
It does NOT matter who I am SENDING TO. This is not a blacklist problem with receiving, this is a problem with my messages getting OUT to ANY sender. I can take a rejected message and send to to another email address and get the exact same rejected message. It does not appear to be rejected by the RECEIVING server becasue if I send to multiple recipients singly, not a spam looking mutliple addresses in the same email, they will all get rejected. Logic says its something in my sending then, not in the receiving. This is the main point all the previous answers seem to miss.
Sometimes I can cut parts of the email and resend and it will go through. Often it comes down to one word, when I take the word out, or put in back in, the message gets sent properly, or not, in reliable pattern that says that word is the problem. Once it was the word "see", once it was "sing", once it was "find"... but if I put on that word in, the message sends.
If I go to the web site and send directly, I have no problems, so we know its not the provider, or the recipients, its something in Outlook. The email is through excite.com if there is some known problem between them and Outlook, but it worked fine for years, so why the sudden problem?
I have up to date virus software and ran another company's scan just to get a second opinion and my computer is virus free, so that's not the problem either. So I'm stumped and frustrated and my productivity crippled when I can't send emails like this.
1) Who is the Outlook "System Adminstrator" and where do those settings/error messages come from?
2) Anyone know a solution to this problem?
