Hoi,
mal die Frage in die Runde : Habt ihr momentan auch Probleme bei der Zustellung von Mails an web.de-Adressen ? Bei uns sammeln sich seit gestern Mails in der Box und gehen nicht raus.
Wenn ich über dnsstuff.com einen DNS-Report aufrufe, bekomme ich bei Mail folgende Meldung :
ERROR: I could not complete a connection to any of your mailservers!
ERROR: mx-ha02.web.de Greeting indicates server is down: 421 mx30.web.de: Too much load; please try again later .
ERROR: mx-ha01.web.de Greeting indicates server is down: 421 mx30.web.de: Too many concurrent SMTP connections from one IP address; please try again later. .
mx-ha02.web.de: The mailserver terminated the connection before the transaction was complete (state 2). This is not RFC compliant, and therefore either due to an error, or it may be the result of a non-RFC-compliant mailserver or non-RFC-compliant anti-spam program.
mx-ha01.web.de: The mailserver terminated the connection before the transaction was complete (state 2). This is not RFC compliant, and therefore either due to an error, or it may be the result of a non-RFC-compliant mailserver or non-RFC-compliant anti-spam program.
If this is a timeout problem, note that the DNS report only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain.
