This should help you get Sendmail installed with basic configuration on Ubuntu.

To find 'yourhostname', just type hostname in the terminal

I'm getting dsn=5.0.0, stat=Service unavailable in my /vatr/log/mail.log, did the exact same steps.

I am getting dsn=4.0.0, stat=Deferred: Connection timed out with alt4.gmail-smtp-in.l.google.com.

thanks!

grrr! embarrassed I needed this but I went arch for a few years and had forgotten my debian setup. Thanks for this. For local mail just add mutt and mailutils and your done.

not working for me.
mail() is returns true, but i'm not getting email at hotmail or gmail.

restart apache2, really? Why would you need to do that?

if lemp server is
sudo service nginx restart
service php7.0-fpm restart

mail() is returning FALSE. Not working for me (Ubuntu 16.04)

I like such blabbering as @m-ric, just to say something ..

on a clean server, do not forget to check whether you need a php-mail:
$ sudo apt-get install php-mail

To be sure, restart the server and execute the configuration with the command:
$ sudo /usr/sbin/sendmailconfig

Checking from the console (with the -v switch being traced):
$ echo 'test message' sendmail -v your@mail.com

You can also configure the settings in the php.ini: '..sendmail_path = /usr/sbin/sendmail -t -i'

I for example set up separately for each virtual host in my_vhost.conf:
<IfModule php[ver]_module>
php_admin_value sendmail_path '/usr/sbin/sendmail -t -i -f admin@example.com'

How can the answer be improved? Stop Skype For Business From Starting Automatically in Windows 10. In case you have been using Skype for Business on your computer, you can make use of the following steps to stop this version of Skype from starting automatically on your Windows 10 Computer. Click on the Windows 10 Start button and then click on Skype For Business App. Both Skype for Windows 10 and for Windows 8 can be configured to stop starting automatically with Windows. However, depending on how you installed the program, the steps for disabling the auto-start feature is different. Stop skype from starting automatically windows 10 2018. With Skype deleted from Startup, it would still start up automatically every 5 or so times I started Windows 10. In the Task Manager (Ctl-Alt-Del), I clicked on the Services tab and found a Skype Updater that was set on Automatic.

..many services, Google for example, require that a PTR record is specified, you can see this in the trace when the test is sent from the console with the key -v

Hi @yfarooq !
Congratulations on the coming New Year!
We would have made the world better if we told how we solved our problems)))
Or not yet solved?
The problem in determining the e-mail address in the listing about this is written, the address should be of the form: some@some.zone(add [.zone] to normal resolve mail address).

Hi All,
sensonicm, How to do it ?
(add [.zone] to normal resolve mail address).

Works for me. Greatly appreciated.

Not working on ubuntu 16.04. It is hanging while trying to generate ssl certificates.

More details here

Really useful, thanks.

@SavaNETgit Hi all!
In the example above there was an address 'reciever@me.com', you need to specify an address with a specific zone, e.g. 'sensonicm@gmail.com' The example did not work because the service could not determine the address.
@youssman
Everything works, look in the internet for information - you need to create a certificate before installation. It hangs during installation on the generation of the certificate. Spend the time, look, I have no time. If you do not find write, I'll find)

getting this error, help will be greatly appreciated.

@elewinso, try to run:

I have to run

The installation will hang on Ubuntu 16.04, the solution is to run these commands:

Reference: https://askubuntu.com/questions/937666/ubuntu-16-04-command-line-sendmail-installation-hanged

Worked fine for me (Ubuntu 18.04), Thanks!

really helpful.
I did only from step 1 to 4,
then it's works like a charm!

my use case is sending internal system(ubuntu 18.04) email notification to users in corporate colleague,
and no need of posfix, just need follow step 1 to 4, fast and neat!

thank you.

I still can't get this to work.

Error: /etc/mail/submit.cf: line 6: invalid argument to V line: 'ERSIONID(Id: startt'
/etc/mail/submit.cf: line 7: invalid argument to V line: 'ERSIONID(Id: autoco'

I tired to comment both line 6 and 7 with # and still can't receive email

'yourhostname' should be long,
that mean, it should have dot com or similar, or you will get error in log:

unable to qualify my own domain name (hostname) - using short name.
