This happened to me and I fixed it by using my isp's smtp server instead of postfix, or by adding a dyndns entry for your host. > > > > -------- Original Message -------- > > Subject: Undelivered Mail Returned to Sender > > Date: Mon, 7 Jun 2004 07:15:26 +0300 (EEST) > > From: [EMAIL PROTECTED] (Mail Delivery System) > > To: [EMAIL PROTECTED] > > > > > > > > This is the Postfix program at host labris2.ttnet.net.tr. > > > > I'm sorry to have to inform you that the message returned > > below could not be delivered to one or more destinations. > > > > For further assistance, please send mail to <postmaster> > > > > If you do so, please include this problem report.

Since you are apparently are on a dynamic connection with no dns entry for a hostname, sympa will not accept a connection. Again, fix it by either entering a dynamic dns entry at a service like dyndns.org or use your isp's smtp servers instead of postfix. -- /g
