Hello alltogether Currently I am trying to set up a Debian Lenny Server, but I am stuck at mail delivery. The server I am trying to set up, has no FQDN, so I used my ISP-Mailserver as a smarthost (I enabled the proper SMTP authentication in exim4). This setup worked a few days, before I suddenly received 451 errors. At first I thought it to be a problem with Exim4, so I switched to postfix. But postfix also gives me the 451 error:
Apr 22 15:53:31 openshoolproxy postfix/smtp[24368]: 413CF26EF9: to=<webserv...@b1online.de>, orig_to=<r...@openshoolproxy>, relay=smtp.strato.com[81.169.145.132]:25, delay=2137, delays=2136/0.05/0.33/0.12, dsn=4.0.0, status=deferred (host smtp.strato.com[81.169.145.132] said: 451 Local Error (in reply to end of DATA command)) To further troubleshoot my problem I used telnet to connect to smtp.strato.com and to send a mail manually. This is what I did: telnet smtp.strato.de 25 Trying 81.169.145.133... Connected to smtp.strato.de.

Independently from my mailserver the telnet command should have succeeded on both machines. But it failed on my debian box. What could be wrong? Is this a problem of my setup, or is my ISP blocking something? Thanks in advance Benedikt -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
