  • Sendmail error (Connection refused by [127.0.0.1])

    From Ali Khoshbin@21:1/5 to All on Wed Jan 12 00:41:02 2022
    Dear Colleagues,
    I am a newbie in Linux Sendmail. I get the below error while trying to send an email via Sendmail by command:

    sendmail user@domain.com < email.txt

    sendmail log is as below:

    Does
    telnet 127.0.0.1 25
    work? (enter quit after getting the greeting)

    Did someone (your OS distribution) change the default port for
    mail submission?
    Check /etc/mail/submit.cf: does it use 587 somewhere?
    If so, either change it back or run sendmail also on that
    port: see cf/README: do not use no_default_msa

    PS: 8.15.2 is pretty old.

    I suppose Validip and invalidip are your ip adresses, but is at least on listening on 127.0.0.1 ??. Doesn't seems so.
    On my Centos 7.9 it loock

    tcp 0 0 localhost:smtp 0.0.0.0:* LISTEN

    could it be that localhost = 127.0.0.1 ?

    It seems like the OP did managed to connect to localhost (127.0.0.1),
    compared to my log there is a big difference on the mailer, for me it's
    relay.

    It's more about his sendmail configuration and I think we need our best mind-readers and scrying glasses to be able to figure out what is
    wrongly configured. Maybe Ali could provide the sendmail.mc

    Hello,
    Excuse me for the long delay.
    Actually I was assigned to another task.
    Now I have moved to setup the sendmail

    My question is that:
    I have added :
    dnl #
    DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
    dnl #

    to my sendmail.mc file but still the server does not listen to port 25 by running command "netstat -ant | grep :25
    "

    Do I have to add the server's valid IP to the sendmail.mc file too?

    Thanks for your suggestions in advance

    telnet 127.0.0.1 25
    and

    Hi,
    I got the "connection refused" while trying to telnet to the IP & ports related to smtp as it shows the sendmail is not listening on this port.
    What should I do?
    Thanks in advance for your priceless help.

    You need to check YOUR file. Or use the standard sendmail.mc provided
    by your distribution and change only the lines you want.
    Please check the part about divert.

    Or you can download and extract it from the tarball from your

    If you need further help, provide info about the OS you use.

    netstat -na -p tcp | egrep '\.(25|587) '


    is sendmail running using /etc/mail/se*cf?

    Really?
    First: there is a ' missing, so your shell should ask for more input...
    Second, which OS?
    If you run Linux instead of *BSD:

    netstat -na -t | egrep ':(25|587)'

    Anyway, did you restart the sendmail daemon?
    If so, is it running?

    ps axuw| fgrep sendmail

    Is there any raw copy of sendmail.mc file avilable for download?

    There are probably millions of them (tried a search engine?)

    You can download the sendmail source code (URL given before) and

    Then you should find out why. I don't know if you properly restarted
    the system and I don't know if you properly processed you mc config.
    These 2 steps are necessary to make the changes work without restarting
    the OS.

    Dear Marco,
