I am the owner of a LISTSERV. One of our subscribers began receiving this rejected posting message:

Your posting to the XXXXX-L list has been rejected because it only contains material in a format disallowed by the list configuration. Even though the list is configured to remove unwanted material and process the remaining text, in this case there would be nothing left after removing the disallowed material. You may want to resend your message in plain text, which is always allowed.

For the previous year and half she was able to post to the LISTSERV without error. She reports nothing has changed with respect to her e-mail account and there are no graphics in her e-mail.

Would you be able to provide me with any information about why the rejected postings occur and most importantly how to solve the problem? Thank you very much, CR
