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

Fine tune the TITLE tag to increase traffic to the site
Improving the TITLE tag is one technique that applies to just about all the search engines. The appearance of key words within the page title is one of the biggest factors determining a Web site’s score in many engines. Changing title of the web pages to include some site keywords which works well with each of the pages can greatly increase the chance of the page getting noticed by the search engines and can increase the page rank of the site as well.
