The problem is that PHP mail   function has a very limited functionality  There are several ways to send mail from PHP    mail   uses SMTP server on your system  There are at least two servers you can use on Windows  hMailServer and xmail  I spent several hours configuring and getting them up  First one is simpler in my opinion  Right now  hMailServer is working on Windows 7 x64  mail   uses SMTP server on remote or virtual machine with Linux  Of course  real mail service like Gmail doesn t allow direct connection without any credentials or keys  You can set up virtual machine or use one located in your LAN  Most linux distros have mail server out of the box  Configure it and have fun  I use default exim4 on Debian 7 that listens its LAN interface  Mailing libraries use direct connections  Libs are easier to set up  I used SwiftMailer and it perfectly sends mail from Gmail account  I think that PHPMailer is pretty good too    No matter what choice is your  I recommend you use some abstraction layer  You can use PHP library on your development machine running Windows and simply mail   function on production machine with Linux  Abstraction layer allows you to interchange mail drivers depending on system which your application is running on  Create abstract MyMailer class or interface with abstract send   method  Inherit two classes MyPhpMailer and MySwiftMailer  Implement send   method in appropriate ways

There are some SMTP servers that work without authentication  but if the server requires authentication  there is no way to circumvent that    PHP s built-in mail functions are very limited - specifying the SMTP server is possible in WIndows only  On  nix  mail   will use the OS s binaries   If you want to send E-Mail to an arbitrary SMTP server on the net  consider using a library like SwiftMailer  That will enable you to use  for example  Google Mail s outgoing servers

When you are sending an e-mail through a server that requires SMTP Auth  you really need to specify it  and set the host  username and password  and maybe the port if it is not the default one - 25    For example  I usually use PHPMailer with similar settings to this ones    mail   new PHPMailer        Settings  mail- gt IsSMTP     mail- gt CharSet    UTF-8     mail- gt Host          mail example com      SMTP server example  mail- gt SMTPDebug    0                         enables SMTP debug information  for testing   mail- gt SMTPAuth     true                      enable SMTP authentication  mail- gt Port         25                        set the SMTP port for the GMAIL server  mail- gt Username      username      SMTP account username example  mail- gt Password      password             SMTP account password example     Content  mail- gt isHTML true                                       Set email format to HTML  mail- gt Subject    Here is the subject    mail- gt Body       This is the HTML message body  lt b gt in bold  lt  b gt     mail- gt AltBody    This is the body in plain text for non-HTML mail clients     mail- gt send      You can find more about PHPMailer here  https   github com PHPMailer PHPMailer

For Unix users  mail   is actually using Sendmail command to send email  Instead of modifying the application  you can change the environment  msmtp is an SMTP client with Sendmail compatible CLI syntax which means it can be used in place of Sendmail  It only requires a small change to your php ini   sendmail path     usr bin msmtp -C  path to your config -t    Then even the lowly mail   function can work with SMTP goodness  It is super useful if you re trying to connect an existing application to mail services like sendgrid or mandrill without modifying the application
