What task should be done to send email from the server?


I am new at linux configuration. My problem is: I do not what tasks should be done to enable sending email from the server. Normally we use contact form where we use php mail() function. I want when I use this function, I would be able to send email. So, please could you guide me anyone as how to configure or which package should be installed.

Moreover, I tried something reading this link and use the following command:

sudo apt-get install sendmail

And then applied this command:

sudo netstat -plutn | grep 25

And find the result:

$ sudo netstat -plutn | grep 25
tcp 0 0* LISTEN 1293/sendmail: MTA:

However, please help what I should do in this circumstance.

Thanks in advance, Shimul

One more thing to try:

sudo apt-get install mailutils

Yes I am getting email using the command: sendmail -v < mail.txt

try a external service and forget about configuration, if you know php you can handle an external service, but if you don’t know how to config a mta service on linux (which can bring you several problems, like open relays, blacklists, etc) then use an external service, I use mandrill which is almost free and pretty good, also gives you a lot of useful information about your email tasks.
