HI,
beim Versuch über meinen (neuen) eigenen postfix den abgehenden Verkehr
abzuwickeln ist mir eine Besonderheit aufgefallen.
Speziell bei einem Mailserver werde ich ständig "gegreylistet" und mir
fallen im Moment nicht viele Dinge ein, warum dem so ist.
Kurz zu meiner Konfiguration:
Der MX hat 'ne feste IP-Adresse und entsprechende DNS Einträge:
dig mx1.nausch.org
; <<>> DiG 9.3.3rc2 <<>> mx1.nausch.org
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 11580
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2
;; QUESTION SECTION:
;mx1.nausch.org. IN A
;; ANSWER SECTION:
mx1.nausch.org. 22784 IN A 88.217.187.21
[michi at michi etc]$ dig -x 88.217.187.21
; <<>> DiG 9.3.3rc2 <<>> -x 88.217.187.21
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 12577
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 5
;; QUESTION SECTION:
;21.187.217.88.in-addr.arpa. IN PTR
;; ANSWER SECTION:
21.187.217.88.in-addr.arpa. 1533 IN PTR mx1.nausch.org.
Soweit sollte doch schon mal alles passen, oder?
O.K., dem postfix habe ich seinen Namen auch entsprechend mitgeteilt:
[root at nss postfix]# postconf myhostname
myhostname = mx1.nausch.org
Im Maillog finde ich jedoch nur laufend Hinweise, dass ich gegreylistet
werde:

Den Zeitstempeln nach kommt mein MX ja auch nicht vor den angesagten 300
Sekunden. Warum werde ich bzw. mein Postfix jedoch nicht akzeptiert? Nach
meinem bisherigen Studium der Postfix-Bibel aka "Das Postfixbuch" habe ich
keine Idee mehr, was ich denn einstellen sollte/dürfte.
Oder liegt das gar nicht an mir, auch nicht beim Ziel-MX sondern an der
DSLeitung in Verbindung mit 'ner festen IP, also nix dyndns oder so 'n
Kram?
Vielleicht hat ja mal jemand 'n Tip für mich. Oder ich melde mich mal ganz
frech beim Postmaster von mx01.udag.de.
ciao,
Michael Nausch
