In an perfect world multipart/alternative is the 'clean' way to send html. Any client who can deal with html displays the text/html part of the message, all other the text/plain part. So if you find a mail of this type you could assume that all (usefull) information is as a copy in the text/plain part. In this case you wouldn't have to reject the message, you just could use the text/plain part for the message that goes to the list. As the world is not perfect (:~( , the best way to deal with this, is to block the mail. multipart/related is the way to embed images (and other objects) that are used in a html part in the mail, so that the mail is selfcontained. > -----Ursprüngliche Nachricht----- > Von: Pier P.
