Email Versand nur von localhost möglich

Hey,

mein Mailserver (Postfix & Dovecot) mit SSL-Zertifikat und konfiguriertem DKIM und SPF empfängt ohne Probleme Mails und versendet diese auch (Port 25 und Port 587 versenden beide mit TLS, Port 465 funktioniert nicht).

Allerdings funktioniert das bisher nur vom Server selbst aus bisher mit PHPMailer.

Über den MailClient Thunderbird empfange ich zwar die alle Mails, kann aber selbst kein versenden.

Die Einstellungen in Thunderbird für den SMTP Server:

Quote

 

Port 587 (25 und 465 bereits probiert)

Verbindungssicherheit: SSL/TLS

Authentifizierungsmethode: Passwort, normal

 

 

Email-Adresse mit Konto ist in Froxlor beim Kundenaccount angelegt.

In Froxlor Admin Panel sind DomainKey-Einstellungen und Domain-SPF-Einstellungen nicht aktiviert.

 

 

Beim Versuch eine Mail zu versenden erhalte ich nach etwa 30 Sekunden einen Timeout.

Die mail.log:

 

Quote

Sep  7 10:21:43 abc postfix/submission/smtpd[21509]: connect from isp.de[1.1.1.1]
Sep  7 10:23:24 abc postfix/submission/smtpd[21509]: lost connection after UNKNOWN from isp.de[1.1.1.1]
Sep  7 10:23:24 abc postfix/submission/smtpd[21509]: disconnect from isp.de[1.1.1.1]

 

Beim erfolgreichen Versenden einer Mail über phpMailer steht das in der mail.log:

Das ist sowieso nur relevant wenn du selbst den nameserver betreibst :)

mydestination = localhost

Diese Zeile in main.cf hat das Problem gelöst

dann hast du aber rumgefummelt, default ist: 

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
