    Hi
    I'm very new to linux so would be greatful if someone could help me resolve this Postfix problem.

    I'm trying to configure Postfix to just send externally (not receive). I'm able to send the messages to postfix however they are stuck in the deferred mail queue.

    When checking with pfqueue, the status of each mail is either "No route to host" or "Connection timed out"
    I've not included a relay host as was trying to send direct, however when I input a relay host, the problem is still the same as being "No route to host" or "Connection timed out".

    I have spoken with my ISP who told me they don't block any ports at all.

    Code:

    traceroute -p 25 mail.google.com
    traceroute to mail.google.com (173.194.34.118), 30 hops max, 60 byte packets
    1 lns1.uan.the.uk.murphx.net (94.30.127.72) 32.387 ms 33.085 ms 34.085 ms

    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.

    old-cyrus unix - n n - - pipe

    flags=R user=cyrus argv=/cyrus/bin/deliver -e -m ${extension} ${user}

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

    See the Postfix UUCP_README file for configuration details.

    uucp unix - n n - - pipe
    flags=Fqhu user=uucp argv=uux -r -n -z -a$sender - $nexthop!rmail ($recipient)

    Other external delivery methods.

    ifmail unix - n n - - pipe
    flags=F user=ftn argv=/usr/lib/ifmail/ifmail -r $nexthop ($recipient)
    bsmtp unix - n n - - pipe

    This isn't a general Postfix support forum - it's for support fo the Postfix Admin package which manages virtual domains for Postfix using a PHP web GUI and MySQL backend.

    You'll probably get a better response over at postfix.org.

      Ok, sorry about that.
      I'll try over there.
