Yes, but the envelope sender is wrong. Mail servers are perfectly justified in refusing mail with an envelope sender containing a non existant domain. Also, if your envelope sender is wrong, you will lose mail. > > Since your address appears to be "j_mini@efn.org", and "efn.org" does > > exist, why don't you just use that? > > well... there is one problem... efn.org is over a 14.4k modem, to my > 28.8k modem, that happens to be dialed into efn's terminal server, but > goes over to a local university which we use for inet connectivity... > so connecting to that host would go over the above, then back from the > university to efn.org... plus, we run FreeBSD on our systems.. so it > is possible, but problematic... considering that he can also dial > directly into efn it would mean needing to have two completely differnt > configurations... Huh? What does this have to do with e-mail addresses? The connectivity is irrelevant. It also has nothing to do with dynamic addresses. Use "-f" flag to sendmail to force the proper envelope sender. > -- > John-Mark Gurney Modem/FAX: +1 541 683 6954 > Cu Networking > > Live in Peace, destroy Micro$oft, support free software, run FreeBSD > Tom
