Hi Frank, Sender: [EMAIL PROTECTED] Precedence: bulk Reply-To: Daniel Roth <[EMAIL PROTECTED]>
the e-mail you've answered was from Roger Bailey. It was not correctly forwarded by me to the list reflector. Sorry for the confusion this may cause. Regards and merry Christmas - - Daniel, sundial mailing list N.B. Background: Sometimes e-mails are bounced by the mailing list software as certain administrative words are used in an e-mail. This is to prevent you all from receiving annoying e-mails like 'unsubscribe me from this mailing list'. See the excerpt of the majordomo's FAQ: "If the message's subject has a word that ends in "subscribe" or "unsubscribe", upper or lower case, it will be bounced. Also, if the first five lines of the message body have the words "add me", "delete me", "subscribe", "sub", "unsubscribe", or "unsub", upper or lower case, anywhere in those lines, the message will be bounced." Obviously this cannot be the reason in this case, but it may be that there is also the word "cancel" on the list of taboo words.
