Hello,I'm having loads of problems while trying to send an e-mail using Outook Express 6 on Windows XP home Edition.The configuration is acording to the one i received from my network provider and it worked perfect until 3 days ago. I just had my LAN "server" (PC) upgraded, reconfigured the Internet Sharing on my network and now sending e-mails using my account on OE is broken. The last time i had this problem, i had only to check My server requires authentication on Outgoing e-mail server. The errors i received varried, and this is the latest one:The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was'Email removed for privacy' . Subject 'tralala', Account: 'mail.b.astral.ro', Server: 'mail.b.astral.ro', Protocol: SMTP, Server Response: '550 5.1.1 <'Email removed for privacy' > recipient rejected 78.96.106.2 is in RBL', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79It's way over my reach to attempt to fix this and i could use some help. Nothing on the internet i found so far really helped, the account setting are the same as before, they should work like normal, the LAN and Inet connections are working properly, and the webclient for the mail acc works fine, but i desperately need to configure ..Thanks in advanceValeriu

You can't fix this. One of the people to whom you addressed the message is using an "RBL" or a Realtime Blackhole List. That's a service that the receiving mail server uses to help it determine whether or not the sending mail agent is coming from a spam-friendly network. Apparently the IP address assigned to your PC by your INternet provider is in a range that your recipient's mail server is rejecting. That recipient will have to address it if they can with their mail service provider.Brian Tillman [MVP-Outlook]------------------------------If a reply helps, please vote it as helpful.

well the thing is that i can't even send an e-mail to myself as well.. and it should work....it did a few days ago, and now it's acting wild.The Ip address assigned to the PC isn't from the INET provider. It's on a local network, with Internet Connection Sharing from my 'server' pc that has an adress assigned by the ISP.
