Problem Outlook fully-qualified hostname

Post by AWOHille » 2012-08-15 21:14

Hallo,

ich habe mit Outlook ein kleines Problem, welches bisher mit noch keiner Outlook Version auftrat. Wie ich im Netz gelesen habe, scheint das bei Outlook sehr sporadisch aufzutreten. Vielleicht gibt es aber ne Lösung, außer den Hostnamen Check in postfix zu deaktivieren:

Code: Select all

postfix/smtpd[9403]: NOQUEUE: reject: RCPT from p5DC5A927.dip.t-dialin.net[93.197.0.0]: 504 5.5.2 <PC>: Helo command rejected: need fully-qualified hostname; from=<info@meine_domain.de> to=<info@meine_domain.de> proto=SMTP helo=<PC>


Warum sendet Outlook nur den Namen des Rechners? Wie kann ich Outlook beibringen, die IP-Adresse des sendenden Rechnes zu verwenden? Oder gibt es eine andere Lösung?

Gruß Hille

Diese Optionen würde ich verwenden, der Rest ist für ein Debian-System OK:

Code: Select all

smtpd_client_restrictions =
  sleep 1,
  permit_mynetworks,
  permit_sasl_authenticated,
  reject_unknown_reverse_client_hostname,
  reject_unauth_pipelining,
  permit
###smtpd_delay_reject = yes
smtpd_data_restrictions =
  permit_mynetworks,
  permit_sasl_authenticated,
  reject_unauth_pipelining,
  permit
smtpd_helo_restrictions =
  permit_mynetworks,
  permit_sasl_authenticated,
  reject_invalid_helo_hostname,
  reject_non_fqdn_helo_hostname,
  reject_unauth_pipelining,
  permit
smtpd_recipient_restrictions =
  permit_mynetworks,
  permit_sasl_authenticated,
  reject_non_fqdn_recipient,
  reject_unknown_recipient_domain,
  reject_unauth_destination,
  reject_unauth_pipelining,
  check_client_access cidr:/etc/postfix/postfix-dnswl-permit,
  check_client_access hash:/etc/postfix/policyd_weight_client_whitelist,
  check_recipient_access hash:/etc/postfix/policyd_weight_recipient_whitelist,
  check_policy_service inet:127.0.0.1:12525,
  check_policy_service unix:private/policy,
  permit
smtpd_sender_restrictions =
  permit_mynetworks,
  permit_sasl_authenticated,
  permit_tls_clientcerts,
  reject_non_fqdn_sender,
  reject_unknown_sender_domain,
  reject_unauth_pipelining,
  check_sender_access regexp:/etc/postfix/tag_as_foreign.re,
  permit

Damit dürfte Dein Problem nicht mehr auftreten.

Leider doch:

Code: Select all

NOQUEUE: reject: RCPT from p5DC5A5CA.dip.t-dialin.net[93.197.0.0]: 504 5.5.2 <PC>: Helo command rejected: need fully-qualified hostname; from=<info@meine_domain.de> to=<info@meine_domain.de> proto=SMTP helo=<PC>


Führt aber nicht genau dieser Teil zum reject?

Code: Select all

smtpd_helo_restrictions =
  reject_non_fqdn_helo_hostname,

Eine mögliche Lösung, funktioniert bei mir seit mehreren Jahren:
Einen DynDNS-Account für den Internetanschluss einrichten und gegebenenfalls den FQDN des DynDNS-Accounts zusätzlich noch in die hosts Datei Deines OS eintragen.



Ich meine zwar vor einigen Jahren Windows direkt einen FQDN verpasst zu haben, kann momentan aber keine passenden Optionen in Win7Pro finden. Vielleicht verwechsle ich das aber auch mit einer alten KDE3-Installation.

Ja, dieser Check könnte die Ursache sein, aber nur dann, wenn Du ohne SMTP-AUTH (SASL) versenden würdest. Mit SMTP-AUTH würde zuerst permit_sasl_authenticated greifen und reject_non_fqdn_helo_hostname gar nicht mehr gefragt, da es hinter permit_sasl_authenticated steht.
Die Reihenfolge der Optionen ist sehr wichtig, denn first-match-wins.
