(third repost, list rejects)
Hi,
I'm having a curious problem with my opensuse alias: my ISP doesn't like it and rejects that mail.
For instance, a test mail sent from gmail to "MY-AKA /at/ opensuse.org", gets a "452 try later" response from my provider, and after a day mx2.suse.de times out and bounces the email:
Reporting-MTA: dns; mx2.suse.de X-Postfix-Queue-ID: 950B344CCA X-Postfix-Sender: rfc822; MY-EMAIL /at/ gmail.com Arrival-Date: Sun, 6 Apr 2008 21:42:08 +0200 (CEST)
Final-Recipient: rfc822; MY-EMAIL /at/ telefonica.net Original-Recipient: rfc822; MY-AKA /at/ opensuse.org Action: failed Status: 4.0.0 Diagnostic-Code: X-Postfix; host tnetmx.telefonica.net[213.4.149.227] refused to talk to me: 452 try later
This smacks more like a client problem than any recipient/sender problem. "refused to talk to me" normally means that the connection is firewalled or the server does not like the client and breaks off immediately after the connect. If it would happen at a later stage Postfix would log either "TIMEOUT after RCPT TO" for a timeout or a reject for helo/mail from/rcpt to/data. What makes this even more mysterious is that the only sensible reject code for that situation would be "421 transmission channel closed". In any case, the telefonica.net server seems rather borked. Either you return a permanent reject code 5xx and hand out a reject message that helps the sender to find out why the mail was rejected or you indeed accept the mail after the temporary problem is solved. This is most probably a telefonica.net problem, and I expect the helpdesk to be completely useless in that situation. -- Sandy List replies only please!
