I've sendmail installed using "apt-get install sendmail" and also postfix installed using Webmin. But Postfix cannot start, and when I checked the /var/log/mail.err

*Jul 11 14:09:03 victoria postfix/master[6588]: fatal: bind 0.0.0.0 port 25: Address already in use
Jul 11 14:09:10 victoria postfix/master[6821]: fatal: bind 0.0.0.0 port 25: Address already in use
Jul 11 14:09:11 victoria postfix/master[6820]: fatal: daemon initialization failure
Jul 11 14:09:12 victoria postfix/postfix-script[6822]: fatal: mail system startup failed*

and my "netstat -tap" show:

disable Sendmail can get the Postfix up and running. But I thought sendmail and postfix are suppose to work together? How to configure to have them both in a server?

Thanks.

  • Could you tell me what would cause this? sendmail.postfix: fatal: [email protected](3301): No recipient addresses found in message header

Postfix is a drop-in sendmail replacement that includes its own sendmail binary (see the foot of this post). I'm honestly surprised apt let you do this, I thought they were package conflicted.

Anyway, to fix:

sudo apt-get purge sendmail
sudo apt-get install --reinstall postfix
sudo /etc/init.d/postfix restart

Proof that sendmail on my system is provided by postfix:

$ dpkg -S `which sendmail`
postfix: /usr/sbin/sendmail

If you're still having problems, here's how you can find out what program (and which package) is hogging port 25:

$ sudo netstat -pel | grep smtp
tcp 0 0 *:smtp *:* LISTEN root 8487 2212/master

$ # Then we use the 2212 from that in the following to get the package:
$ dpkg -S "$(sudo ps ux | grep 2212 | awk '{print $NF}')"
postfix: /usr/lib/postfix/master

In my case that's postfix. In your case I expect to see something else. Nuke it from orbit.

  • Hi, thanks for your help. I have follow your instruction, but still getting the same error =========================================================== Jul 11 19:10:59 victoria postfix/master[15150]: fatal: bind 0.0.0.0 port 25: Address already in use Jul 11 19:11:48 victoria postfix/master[15432]: fatal: bind 0.0.0.0 port 25: Address already in use Jul 11 19:11:49 victoria postfix/master[15431]: fatal: daemon initialization failure Jul 11 19:11:50 victoria postfix/postfix-script[15433]: fatal: mail system startup failed Any idea? maybe is not the sendmail this time?

    hey, thanks for your help. I restart my server and the postfix is started and no more error from the log! Thanks! Jul 11, 2013 at 12:07

For me the solituion was a variant of Oli answer in an Ubuntu13:

Error: fatal: bind 0.0.0.0 port 25: Address already in use

Sendmail purge didn't work:

Package 'sendmail' is not installed, so not removed

So I tried:

service sendmail stop
sudo apt-get install --reinstall postfix

and worked!

  • sudo service postfix stop did the trick for me. Then a sudo /etc/init.d/postfix reload succeeded. Jun 12, 2014 at 21:08
  • if it says Package 'sendmail' is not installed, so not removed, you should run sudo apt-get purge sendmail* Apr 15, 2017 at 10:13

This solved me on the same issue.

service sendmail stop
service postfix restart
service sendmail start

As seen at Postfix start error Port 25: Address already in use
