Method 1:
$ mail -s “Subject: Test email from linux server” info@test.com
Press the “Return” key
Enter the body part of the email
Press ctrl + D
Enter a CC email if you would like (e.g. info2@test.com)
Press ctrl + D again
Then check the mail box to see if the mail has arrived.
Many email servers depend on Reverse DNS in order to identify if the mail is legit or spam. For the Reverse DNS to work correctly, two points need to be addressed
a) Look for IP address of the mail server should return its name. PTR record should be set for this
b) Reverse look on the name should return back the IP address
For example,
$ dig -x 217.83.122.34
;; ANSWER SECTION:
34.122.83.217.in-addr.arpa. 66372 IN PTR mail.example.com.
$ dig mail.example.com
;; ANSWER SECTION:
mail.example.com. 900 IN A 217.83.122.34
Check the IP address that is getting resolved matches the name that is getting returned back.
First Check PHP version that is currently installed

When transitioning MySQL database from Windows to Linux, users often encounter issues related to case-sensitiveness. Windows is case-insensitive and Linux is case-sensitive.
In such scenarios when a database call is made after the application migration happens, users often run into errors which can send them in circles between the migration servers.
Solution to this problem is to add a single line of text under my.cnf (MySQL configuration file) under [mysqld] (more…)

In certain scenarios, users encounter above message when they try to connect to their web hosting accounting using one of their ftp programs like filezilla, ws-ftp, cuteftp, smartftp
Solutions that seemed to have worked for me
i) Host name: Try adding ftp://www.mysite.com and set the port to 21
ii) User name: Try typing username@domain.com instead of just the user name of the ftp user
There are different variants of Linux in the market like RedHat, Debian, CentOS, Ubuntu, Mandrake, Suse and a Linux beginner often ponder why they call Linux distributions by various names. The kernel or the heart of all the distributions is Linux and in bringing it to different market usage different community or vendors have adopted the kernel to serve that purpose.
