Using Gmail and MSMTP To Send Mail From PHP

Posted: 2014-06-20 18:16:35

1. Enabled IMAP access under your Gmail account, to be able to connect to Gmail via something other than its web interface:

Settings - Forwarding and POP/IMAP - IMAP Access - Enable IMAP - Save Changes

gmail-imap-access

2. Set PHP to use MSMTP as “sendmail”:

Edit file php.ini (C:\WampDeveloper\Config\Php\php.ini)

Disable mail()’s default use of a local mail server.

;SMTP = localhost
;smtp_port = 25

* Comment the above lines for SMTP and smtp_port by using the “;” character.

Enable mail()’s use of MSMTP.

sendmail_path = "C:/WampDeveloper/Tools/msmtp/msmtp.exe -d -C C:/WampDeveloper/Tools/msmtp/msmtprc.ini -t --read-envelope-from"

mail.log = "C:/WampDeveloper/Logs/Php/maillog.txt"

* Uncomment the above lines by removing the “;” character. And make sure to update the paths to the correct drive letter.

3. Define your Gmail account information for MSMTP to use (using Gmail’s outgoing mail settings):

Edit file msmtprc.ini (C:\WampDeveloper\Tools\msmtp\msmtprc.ini)

# Default values for all accounts
defaults
tls_certcheck off
logfile C:/WampDeveloper/Tools/msmtp/msmtplog.txt

* Make sure to update the logfile path to the correct drive letter.

account Gmail
host smtp.gmail.com
port 587
auth on
tls on
from my.email@gmail.com
user my.email@gmail.com
password mypassword

* Update the above lines with your email address and password.

4. Send a test email:

Create file C:\WampDeveloper\Websites\www.example.com\webroot\send-email.php

Set the proper “$from” and “$to” email addresses.

<?php
  $from    = 'my.email@gmail.com';
  $to      = 'someone.else@somewhere.else';

  $subject = 'Test Subject';
  $message = 'Hello. Testing email.';
  $headers =
    'From: ' . $from . "\r\n" .
    'Reply-To: ' . $from . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

  if(mail($to, $subject, $message, $headers))
    echo 'Mail function returned successfully. Mail has probably been sent.';
  else
    echo 'Error! Mail function failed. Mail NOT sent.';
?>

* Make sure that your “From:” email address matches the email address defined for Gmail in msmtprc.ini. You cannot use another email address (Gmail will reject it).

Access URL http://www.example.com/send-email.php

Then check your Gmail’s Sent folder, and your receiving account’s Inbox and Spam folder.

5. Debugging MSMTP:

If you do not receive your test email, and your Gmail account does not have a copy of the email in its Sent folder, check MSMTP’s log file for clues (msmtplog.txt).

You can also test sending a basic email directly from the command line (to bypass PHP) to see if MSMTP is working itself (it will output debug info)…

echo Subject: Testing Email. | C:\WampDeveloper\Tools\msmtp\msmtp --debug --file=C:/WampDeveloper/Tools/msmtp/msmtprc.ini --logfile=C:/WampDeveloper/Tools/msmtp/msmtplog.txt --from=my.email@gmail.com -t someone.else@somewhere.else

* Update the above paths, and the “from” (my.email@gmail.com) and “to” (someone.else@somewhere.else) email addresses. This email will only have a subject line, it will not have a body due to the limitations of the command line.
