    Exclamation Trying to send up port 587 on sendmail

    I have a private email server, normally I used squirrelmail to access it, but I would like to use thunderbird.

    Thunderbird want access to port 587 if I use STARTLS.

    The version of sendmail provided on Lubuntu 12.04, only provides access to port 587 using localhost.

    I want access to domain-name 587, so I can use a laptop when working from a customer site.

    It looks like all you should do is to remove the no_default_msa, and type make and reload the configs.
    Doing this, generates a message about 'opendaemonsocket: deamon MSA: can not bind: Address already in use, sendmail then dies with a message about SMTP socket wedged: exit

    SO does anybody known how to configure sendmail so that it will accept non localhost connections on port 587?
    I have looked on the wider net, but most of the answers either do not work or are several years out of date!

    The follwoing row from

    DAEMON_OPTIONS(`Family=inet, Name=MSP-v4, Port=submission, M=Ea, Addr=')dnl

    Should become

    DAEMON_OPTIONS(`Family=inet, Name=MSP-v4, Port=submission, M=Ea')dnl

    Good luck!

    You also have to rebuild and restart sendmail itself. I usually use symbolic links in the /etc/mail directory like this:

    cd /etc/mail
    sudo m4 < >
    sudo mv
    sudo ln -s
    sudo service sendmail restart
    Then if something goes wrong it's easy to revert to just by repointing the symlink.
