Ist mail.gmx.net:587 down?

[Anton Blau]

Hallo,

seit heute Morgen kann mein Smart-Host keine E-Mails mehr an
mail.gmx.net ausliefern.

mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
002168687 2864 Tue Jun 9 22:43:04 MAILER-DAEMON
(connect to mail.gmx.net[212.227.17.190]:587: Connection
timed out)

-- 2 Kbytes in 1 Request.

1. Kann es sein, dass mail.gmx.net:587 down ist?
2. An wen wendet man sich da?


Viele Grüße

tony

Vielen Dank. Aufgrund Deiner Info habe ich bemerkt, dass meine Firewall
die Ursache war.

Schönen Feiertag!
