[ERLEDIGT] SMTP Timeout
Hallo zusammen,

ich habe da ein kleines Problem mit meinem SMTPD.
Meinen vServer habe ich von Anfang an mit ispCP und debian aufgesetzt und bis vor kurzem lief auch alles mit dem smtpd noch ganz normal. Ich weiß nicht genau wann "es" kaputt gegangen ist weil ich den smtp eigentlich fast nie nutze sondern nur über imap Mails empfange.

Jedenfalls habe ich festgestellt, dass es nicht mehr funktionierte weshalb ich mal einen Blick in die Logs geworfen habe und dabei rausgefunden, dass es ihm offenbar an SSL-Zertifakten mangelte, denn der Fehler war immer in der Art "no certs found". Also habe ich den Guide von http://www.isp-control.net benutzt um openssl zu installieren und den smtpd (postfix) mit entsprechenden Zertifikaten auszustatten. Hat auch soweit alles geklappt.

Dummerweise jedoch, wenn ich nun versuche eine E-Mail zu senden lädt sich jedes E-Mail-Programm tot und kann die Mail nicht versenden.



Die Logs sagen dazu:

Kommentiere ich die TLS-Konfiguration aus, beschränkt sich das Log auf:

Leider habe ich keine Ahnung was ich nun tun soll bzw. warum dieser Fehler auftritt. Ich hoffe, dass mir jemand von euch helfen kann.
Da das MyBB meine Attachments irgendwie nicht mag, könnt ihr die main.cf hier einsehen: http://baiji.eu/main.cf

RE: SMTP Timeout
hey,

nein nein es läuft schon RC6, aber die erste Installation ist halt von RC3-Zeiten und daher steht das wohl noch in der main.cf als "banner" Wink

Also in der mail.err steht zu deinem Test-Versuch gar nichts. Der letzte Eintrag dadrin ist schon mehr als eine Woche alt und ist noch von den Zeiten der fehlenden Zertifikate.

In der mail.log steht allerdings folgendes:

vielleicht hilft das ja weiter.

RE: SMTP Timeout
es Sieht so aus als versucht apple mail über SMPTS (secure) zu versenden Check mal deine Config am client ob es da aktiviert ist und wenn ja deaktvieren wenns hilft hat dein Apple Mail evtl. probleme mim self signed certifikat oder ähnliches.

RE: SMTP Timeout
Nun, ich habe eigentlich nichts geändert an Apple Mail, aber nun funktioniert es anstandslos...
Herzlichen Dank!!!!! :-)

Eine Frage/Problem habe ich dann aber nun dennoch wegen des noplaintext. Im Grunde ist mir das ein bisschen unsicher. Gibt's ne Lösung dafür?
