    Problema invio posta tramite server postfix + dovecot su host ovh VPS

    Buona sera a tutti amici del forum.

    Ho preso una vps cloud su ovh.

    Tramite loro ho preso anche un dominio (jcservice.it ) ma non ho attivato servizi mail o hosting.

    Dalla gestione dns ho impostato il dominio che punta sulla mia vps e i record MX sempre sulla mia vps.

    La parte web con apache 2 + php + mysql funziona perfettamente tranne l'invio delle mail (in ricezione ok)

    Ho configurato postfix e dovecot ma nonostante tutto non riesco a mandare email.

    Ho preso i certificati tramite let's encrypt per autenticarmi tramite tls.

    Dai log ottengo questi errori durante l'invio:

    vps612313 postfix/smtpd[9918]: connect from net-2-32-61-234.cust.vodafonedsl.it[2.32.61.234 ]

    Questa è la mia configurazione del main.cf :

    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 (Debian/GNU)
    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

    compatibility_level = 2

    TLS parameters

    smtpd_tls_cert_file=/etc/letsencrypt/live/mail.jcservice.it/cert.pem

    Questa è la configurazione del master.cf:

    of the file, see the master(5) manual page (command: "man 5 master" or

    Do not forget to execute "postfix reload" after editing this file.

    Interfaces to non-Postfix software. Be sure to examine the manual

    pages of the non-Postfix software to find out what options it wants.

    Many of the following services use the Postfix pipe(8) delivery

    agent. See the pipe(8) man page for information about ${recipient}

    and other message envelope options.

    ====================================================================

    maildrop. See the Postfix MAILDROP_README file for details.

    Also specify in main.cf: maildrop_destination_recipient_limit=1

    maildrop unix - n n - - pipe
    flags=DRhu user=vmail argv=/usr/bin/maildrop -d ${recipient}

    ====================================================================

    Recent Cyrus versions can use the existing "lmtp" master.cf entry.

    Specify in cyrus.conf:

    lmtp cmd="lmtpd -a" listen="localhost:lmtp" proto=tcp4

    Specify in main.cf one or more of the following:

    mailbox_transport = lmtp:inet:localhost

    virtual_transport = lmtp:inet:localhost

    ====================================================================

    Cyrus 2.1.5 (Amos Gouaux)

    Also specify in main.cf: cyrus_destination_recipient_limit=1

    #cyrus unix - n n - - pipe

    user=cyrus argv=/cyrus/bin/deliver -e -r ${sender} -m ${extension} ${user}

    ====================================================================

    Old example of delivery via Cyrus.

    Normalmente la configurazione di Postfix non è una cosa banale, nel senso che richiede accortezza e file di configurazione precisi. Credo che faresti meglio o seguire qualche tutorial su howtoforge o simili o eventualmente chiedere consulenza professionale sistemistica.
