---------------------------IETF Mailing Draft--------------------------- - (1) This header field should From (not not standardized never appear in e-mail being followed by a for use in e-mail sent, and should thus not appear colon) in this memo. It is however included, since people often ask about it. "not standardized Used to mark header fields defined only in RFC for use in e-mail" 1036 for use in Usenet News. These header fields have no standard meaning when appearing in e-mail, some of them may even be used in different ways by different software. When appearing in e-mail, they should be handled with caution. Note that RFC 1036, although generally used as a de-facto standard for Usenet News, is not an official IETF standard or even on the IETF standards track. ---------------------------------------------------------------------- This may or may not be justification for refusal, I can't say for sure. My recommendation would be to avoid using potentially problematic fields, of which From (without the colon) seems to definately qualify. > If I set the visible name to mindspring.com, then the from looks like: > > from <[EMAIL PROTECTED]> > > Mindspring inserts a return path: > > Return-Path: <[EMAIL PROTECTED]> > > so my returned mail will go to another user. Regarding lee.bradswhaw going to bradshaw, I thought I read that a dot in this field was not standard and that it "may" be rewritten "if necessary", however I cannot find that now. Again, my impression is that this qualifies as a potentially problematic field entry, and it would be best to avoid the dot. I'm not an authority in this matter, I'm just calling it like I see it. -- David Stern ------------------------------------------------------------------ http://weber.u.washington.edu/~kotsya [EMAIL PROTECTED] -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
