Hallo liebe Leute,
nachdem ich meinen Mailserver von OpenBSD 5.1 auf 5.2 aktualisiert habe,
möchte der local Daemon keine Mails an den Cyrus-IMAP abliefern. Postfix
beschwert sich dann mit der folgenden Fehlermeldung:
<snip>
postman postfix/smtpd[26245]: warning: SASL authentication failure: no
user in db
postman postfix/smtpd[26245]: NOQUEUE:
client=xxx.xxx.xxx.xxx.net[xxx.xxx.xxx.xxx], sasl_method=PLAIN,
sasl_username=foobar at domain.org
...
postman postfix/local[2037]: warning: error looking up passwd info for
foobar: Operation not permitted
...
postman postfix/local[2037]: 8BF9B51480F:
to=<foobar at mailserver.domain.org>, orig_to=<foobar at domain.org>,
relay=local, delay=0.07,
delays=0.05/0.01/0/0.01, dsn=4.0.0, status=deferred (user lookup error)
...
<snap>
Die Meldung "SASL authentication failure: no user in db" vom smtpd kann
ich nicht so recht einordnen. Denn der folgende Test ist erfolgreich:
<snip>
# openssl s_client -connect <meinmailserver>:25 -starttls smtp
verify error:num=18:self signed certificate
...
---
250 8BITMIME
AUTH PLAIN DASGEHEIMEPASSWORT
235 2.7.0 Authentication successful
<snap>
Meine Konfiguration sieht wie folgt aussieht. Klienten authentifizieren
sich per sasl2db. Die scheint wie oben zu sehen auch zu klappen. Mails
werden per lmtp (unix socket) an den cyrus-imap abgeliefert. Und hier
scheint es dann zu klemmen. Der Socket befindet sich in
/var/spool/postfix/public/ und hat die korrekten Rechte root:_postdrop.
Da ich an der Konfiguration nichts geändert habe, außer eben ein Update
von Postfix 2.8.8 auf Postfix 2.9.3, cyrus-imap-2.4.13 auf
cyrus-imapd-2.4.16p0 sowie cyrus-sasl-2.2.25p2 auf cyrus-sasl-2.1.25p3
vermute ich eine Inkompatibilität zwischen den neuen Versionen.
Gibt es eine Möglichkeit wie ich lmtp zwischen Postfix und Cyrus
sinnvoll testen kann, bzw. weiß vielleicht jemand woran es hapern könnte?
Vielen Dank im Voraus,
Gruß Jörg
