Hallo,

Ich habe mich schon halbtot gegoogelt aber ich finde den Fehler nicht:
Thunderbird und weitere Anndroid-Clients verbinden sich problemlos auf Port 993 (Eingang) und Port 587 (Ausgang)

Sobald ich Outlook 2010 nutzen will wird der Zugang zu 993 komplett blockiert.
Auch das Log (/var/log/mail) gibt keine(!) Meldung aus!

Was mich irritiert ist, dass es keinerlei Log-Einträge bei den Einlogversuchen auf Port 993 gibt.
Anm: Unverschlüsselt funktioniert der Mailabruf überigens (Port 143, Courier-Imap)

Hier die configs von Postfix und Courier-IMAP-SSL

# WARNING: Peer certificate verification has NOT yet been tested. Proceed

##NAME: TLS_STARTTLS_PROTOCOL:0
#
# TLS_STARTTLS_PROTOCOL is used instead of TLS_PROTOCOL for the IMAP STARTTLS

TLS_STARTTLS_PROTOCOL=TLS1

##NAME: TLS_CIPHER_LIST:0
#
# TLS_CIPHER_LIST optionally sets the list of ciphers to be used by the

# TLS_DHCERTFILE - PEM file that stores our Diffie-Hellman cipher pair.
# When OpenSSL is compiled to use Diffie-Hellman ciphers instead of RSA

##NAME: TLS_CERTFILE:0

# TLS_CERTFILE - certificate to use. TLS_CERTFILE is required for SSL/TLS

##NAME: TLS_TRUSTCERTS:0
#
# TLS_TRUSTCERTS=pathname - load trusted certificates from pathname.

# contain a list of trusted certificates, in PEM format. If a
# directory, the directory should contain the trusted certificates,
# in PEM format, one per file and hashed using OpenSSL's c_rehash

# TLS_VERIFYPEER - how to verify client certificates. The possible values of

Sobald ich Outlook 2010 nutzen will wird der Zugang zu 993 komplett blockiert.
Auch das Log (/var/log/mail) gibt keine(!) Meldung aus!


wenn nichts in den logs steht, dann verbindet sich der client nicht.
ist evt. eine firewall/virenscanner,... auf den client installiert, der die verbindung blockiert.

oder steht evt. in den anderen logs was?
messages, warn, mail.error....

Versuch doch mal mit Wireshark (oder per Telnet) den Verbindungsaufbau auf Clientseite zu loggen.... oder mit der SSL Version des SendEmail Perl Skriptes....

(Schade dass die meisten Clients keine Log Funktion zu besitzen scheinen...)

Vielen Dank für die Antworten.

Grundsätzlich funktioniert Port 993. Thunderbird kann sich ja erfolgreich connecten.
Es scheinen nur MS Clients (Outlook,Win8 Mail App) Probleme zu machen.

CA Probleme ? Ich weiß ja nicht was MS Programme machen wenn das Zertifikat für die SSL Verbindung nicht von einer eingetragenen CA Autorität unterschrieben wurde. Vielleicht kannst du in dem Fall das Zertifikat des Servers direkt in die Programme importieren lassen ....

Ich habe so extra bei Comodo ein Zertifikat geholt, welches auch in anderen Programmen (IE, Firefox, Thunderbird) ohne Probleme akzeptiert wird.
Es scheint wirklich nur an Port 993 und dem dahinterliegenden Courier-IMAP-SSL zu liegen... ich werd noch wahnsinning...
