Ich versuche, einen Postfix + Dovecot-Mailserver auf meinem eigenen Server zu installieren und habe Probleme beim Empfangen von E-Mails. Ich habe dieses Tutorial befolgthttps://samhobbs.co.uk/2013/12/raspberry-pi-email-server-part-1-postfix(zusammen mit einigen anderen). Wenn ich Thunderbird verwende, kann ich mich mit meinem Server verbinden und E-Mails versenden. Eingehende E-Mails werden jedoch nicht empfangen.
So sieht meine Postfix-main.cf aus:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# TLS parameters
smtpd_tls_cert_file = /etc/ssl/certs/server.crt
smtpd_tls_key_file = /etc/ssl/private/server.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
myhostname = embe-it.de
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = embe-it.de, h2535210.stratoserver.net, localhost.stratoserver.net, , localhost
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
home_mailbox = Maildir/
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
#smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
#smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
#smtpd_client_restrictions = permit_networks, permit_sasl_authenticated, reject_unknown_client_hostname
#smtp_tls_security_level = may
#smtpd_tls_security_level = may
smtp_tls_note_starttls_offer = yes
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_auth_only = yes
Und dies ist die master.cf (um SMTPs zu aktivieren):

Für Dovecot habe ich 10-master.conf bearbeitet:
# ...
service imap-login {
inet_listener imap {
port = 143
}
inet_listener imaps {
port = 993
ssl = yes
}
# Number of connections to handle before starting a new process. Typically
# the only useful values are 0 (unlimited) or 1. 1 is more secure, but 0
# is faster. <doc/wiki/LoginProcess.txt>
#service_count = 1
# Number of processes to always keep waiting for more connections.
#process_min_avail = 0
# If you set service_count=0, you probably need to grow this.
#vsz_limit = $default_vsz_limit
}
# ...
10-auth.conf:
# ...
disable_plaintext_auth = no
auth_mechanisms = plain login
# ...
Und schließlich SSL in 10-ssl.conf aktiviert (mit Standardzertifikat):
# ...
ssl = required
# ...
Meine Domain ist embe-it.de auf Ubuntu 14.04. Ich habe einen Benutzer namens Marvin und das Maildir erstellt, das jetzt von Dovecot erstellte Dateien sowie drei Verzeichnisse namens cur, new und tmp enthält. Das Protokoll zeigte die ausgehenden Mails, aber keine Fehler für eingehende (und jetzt, nachdem ich es gelöscht und eine leere Datei neu erstellt habe, ist es nicht mehr gefüllt). Ich habe die Verbindung per Telnet getestet (sowohl lokal als auch remote), was funktioniert hat.
Haben Sie Vorschläge?
Antwort1
Gelöst durch Neuinstallation und Neukonfiguration von allem. Ich weiß nicht genau, was es war.
