Install PHP Pear Mail / SMTP package on CentOS / Red Hat Enterprise Linux

Recently I’ve noticed that Redhat removed support for following php pear packages:

a) NET/SMTP : An implementation of the SMTP protocol

b) Mail : Class that provides multiple interfaces for sending emails

c) Net/Socke : Network Socket Interface

The simplest solution is downloading and installs these files from php pear repo.

Step # 1: Download files

Use wget command to download all files:
# cd /tmp
# wget http://download.pear.php.net/package/Mail-1.1.14.tgz
# wget http://download.pear.php.net/package/Net_SMTP-1.2.10.tgz
# http://download.pear.php.net/package/Net_Socket-1.0.8.tgz

Untar all files:
# tar -zxvf Mail-1.1.14.tgz
# tar -zxvf Net_SMTP-1.2.10.tgz
# tar -zxvf Net_Socket-1.0.8.tgz

Step # 2: Install files

Simply copy file to your webroot such as /www/usr/share/pear or standard location such as /usr/share/pear:
# cd /usr/share/pear
# mkdir Net
# cd Net
# cp /tmp/Net_SMTP-1.2.10/SMTP.php .
# cp /tmp/Net_Socket-1.0.8/Socket.php .
# cd ..
# cp -avr /tmp/Mail-1.1.14/Mail/ .
# cp -avr /tmp/Mail-1.1.14/Mail.php .

Step # 3: Test SMTP email

Now you have required files, all you have to do is send email using authenticated smtp server.

    I installed RedHat 5.3 and I found the same problem with others packages. To solve it I installed php-pear and from command line I installed additional packages, for example:

    # pear install Mail
    # pear install DB

    I did it with other packages and worked very well.



  • To install PEAR MAIL package you can use:

    /usr/local/bin/pear install Mail
    /usr/local/bin/pear install Net_SMTP
    /usr/local/bin/pear install Net_Socket

    This guide helps a lot. Thanks for that. Please correct the type at step 1.


    # http://download.pear.php.net/package/Net_Socket-1.0.8.tgz


    #wget http://download.pear.php.net/package/Net_Socket-1.0.8.tgz

    why would you need to untar and copy files?
    all you need to do after download the package is just : pear install downloaded_page_name.tgz
    specifically, when you install Net_SMTP, add this at the end: –alldeps
    it will install Net_Socket for you as well.
