[SOLVED] Postfix status=deferred (mail transport unavailable)

Hi there.
I trying to make work posfix to recibe mail, but it's not work.
I'm on:

• openSUSE 20150612 Tumbleweed
• ISPConfig-3.0.5.4p8.
• postfix-2.11.5-2.1
• dovecot-2.2-3.2

amavis is working and I can send mails without problems.

Any suggestions?

Your master.cf seems to not have the dovecot setup properly.
Should have something similar to:

Code:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${user}@${nexthop}

instead of ${recipient} ${user} ${nethop} ${sender} ${extension} $(recipient) ${user} etc etc

 

Thanks!, that solve my problems and it's working now
Maybe there is a problem in ISPConfig installer in "opensuse.lib.php" file at this lines:

PHP:

        if(!stristr($content, "dovecot/deliver")) {
            $deliver_content = 'dovecot   unix  -       n       n       -       -       pipe'."\n".'  flags=DROhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}';
            af($conf["postfix"]["config_dir"].'/master.cf', $deliver_content);
        }

If in the master.cf there are the config lines but commented (OpenSuSE case) the condition "!stristr($content, "dovecot/deliver")" won't work, this proposal will work in this conditions:

PHP:

        if(!preg_match('/\n[^#]*dovecot\/deliver/', $content)) {
            $deliver_content = 'dovecot   unix  -       n       n       -       -       pipe'."\n".'  flags=DROhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}';
            af($conf["postfix"]["config_dir"].'/master.cf', $deliver_content);
        }

Thank you very much!

 

It seems, that the installer for opensuse doesn´t work as expected. I will check this.
Can you post the lda-part from your dovecot.conf?

 

In OpenSuSE the dovecot.conf file is all lines commented exept :

Code:

dict {
  #quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext
  #expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf.ext
}

# Most of the actual configuration gets included below. The filenames are
# first sorted by their ASCII value and parsed in that order. The 00-prefixes
# in filenames are intended to make it easier to understand the ordering.
!include conf.d/*.conf

# A config file can also tried to be included without giving an error if
# it's not found:
!include_try local.conf

And the lda part is in the /etc/dovecot/conf.d/15-lda.conf file and this is the content:

Code:

##
## LDA specific settings (also used by LMTP)
##

# Address to use when sending rejection mails.
# Default is postmaster@<your domain>. %d expands to recipient domain.
#postmaster_address =

# Hostname to use in various parts of sent mails (e.g. in Message-Id) and
# in LMTP replies. Default is the system's real hostname@domain.
#hostname =.

# If user is over quota, return with temporary failure instead of
# bouncing the mail.
#quota_full_tempfail = no

# Binary to use for sending mails.
#sendmail_path = /usr/sbin/sendmail

# If non-empty, send mails via this SMTP host[:port] instead of sendmail.
#submission_host =

# Subject: header to use for rejection mails. You can use the same variables
# as for rejection_reason below.
#rejection_subject = Rejected: %s

# Human readable error message for rejection mails. You can use variables:
#  %n = CRLF, %r = reason, %s = original subject, %t = recipient
#rejection_reason = Your message to <%t> was automatically rejected:%n%r

# Delimiter character between local-part and detail in email address.
#recipient_delimiter = +

# Header where the original recipient address (SMTP's RCPT TO: address) is taken
# from if not available elsewhere. With dovecot-lda -a parameter overrides this..
# A commonly used header for this is X-Original-To.
#lda_original_recipient_header =

# Should saving a mail to a nonexistent mailbox automatically create it?
#lda_mailbox_autocreate = no

# Should automatically created mailboxes be also automatically subscribed?
#lda_mailbox_autosubscribe = no

protocol lda {
  # Space separated list of plugins to load (default is global mail_plugins).
  #mail_plugins = $mail_plugins
}

Share the folder with many config files
ls /etc/dovecot/conf.d/

Code:

10-auth.conf  20-lmtp.conf  auth-deny.conf.ext
10-director.conf  20-managesieve.conf  auth-dict.conf.ext
10-logging.conf  20-pop3.conf  auth-ldap.conf.ext
10-mail.conf  90-acl.conf  auth-master.conf.ext
10-master.conf  90-plugin.conf  auth-passwdfile.conf.ext
10-ssl.conf  90-quota.conf  auth-sql.conf.ext
15-lda.conf  90-sieve.conf  auth-static.conf.ext
15-mailboxes.conf  90-sieve-extprograms.conf  auth-system.conf.ext
20-imap.conf  auth-checkpassword.conf.ext  auth-vpopmail.conf.ext

but after the ISPconfig installation the dovecot.conf look like a this:

Code:

listen = *,[::]
protocols = imap pop3
auth_mechanisms = plain login
disable_plaintext_auth = no
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_privileged_group = vmail
ssl_cert = </etc/postfix/smtpd.cert
ssl_key = </etc/postfix/smtpd.key
ssl_protocols = !SSLv2 !SSLv3
passdb {
  args = /etc/dovecot/dovecot-sql.conf
  driver = sql
}
userdb {
  args = /etc/dovecot/dovecot-sql.conf
  driver = sql
}
plugin {
  quota = dict:user::file:/var/vmail/%d/%n/.quotausage
  sieve=/var/vmail/%d/%n/.sieve
}
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  unix_listener auth-userdb {
    group = vmail
    mode = 0600
    user = vmail
  }
  user = root
}
service imap-login {
  client_limit = 1000
  process_limit = 500
}
protocol imap {
  mail_plugins = quota imap_quota
}
protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
  mail_plugins = quota
}
protocol lda {
  mail_plugins = sieve quota
}

I had to add the "postmaster_address" manually in the protocol lda section

 

That´s what i wanted to know. Thanks. Currently i have no idea why you need this with OpenSUSE. On Debian you don´t need this value.

BTW: i don´t like the way the installer / updater checks postfix´s master.cf. Using grep or somethin similar may work.
Maybe we can switch to "postconf -M dovecot.unix" to detect the service dovecot in postfix.
