How to manage postfix queue so that I'll send email just on request

    Hi to everybody.
    I've create a main mailserver and a local mailserver.
    The local mailserver will relay all the emails to be sent to the main mailserver, that phisically do the job.
    The local mailserver will fetch the email arrived from the main mailserver with fetchmail.
    Now, this is the issue:
    I've setup the local mailserver so that every email to be sent is relay to the main mailserver. But I don't want that every email is relayed automatically... I want to use the queue of postfix and put all the email in "hold", so that, with a script, I'll send manually every email.

    How to setup the queue to put the emails in "hold" and not send them directly?

    This is the that I've now:
    # See /usr/share/postfix/ 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 (Debian/GNU)
    biff = no
    # appending .domain is the MUA's job.

    After an afternoon on google I've found something what should be ok:
    -I'll add in
    hold unix - - n - - smtp
    -I'll add in this lines:
    -in, where there is:
    transport_maps = proxy:mysql:/etc/postfix/
    I'll write in that database
    instead of
    Now all the emails that I'll try to send from the local mailhost are queued in deferred transport and I've to send them manually.
    The only thing now is: how can I put all the email that I'll try to send to "hold" insted of "defer"?
    I know the command to do it one by one, but I would like to have this configuration directly by postfix...

    Guys, for some reason with my configuration I can try to send email just with telnet 25 (SMTP), but If I'm trying to telnet the POP3 or IMAP, I've a login error...

    Any suggestions?

    nice monologue you're having here ;-)

    anyway, may i asked why you want a delay in sending email?
    you know how annoying that it? ;-)

    Yes it was a monologue... :p
    I need to make a queue of emails because this mailserver will be connected on internet with a very expensive connection...

    Any idea of why I'm having login error with POP3?

    Check if those processes are running

    netstat -tapn | grep ':25'
  8. voltron81

    voltron81 New Member

    Yes the processes are running:
    tcp        0      0    *               LISTEN      4747/master
    tcp        0      0   *               LISTEN      2336/couriertcpd
    I can send email via telnet 25, but if I telnet 110, I can not login...

    i'd say courier :)

    tcp        0      0   *               LISTEN      2336/couriertcpd

    thanks guys, but I solved.
    It was a pop3 and IMAP certificate issue...
