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
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
* Make sure to update the logfile path to the correct drive letter.
* 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.
$from = 'email@example.com';
$to = 'firstname.lastname@example.org';
$subject = 'Test Subject';
$message = 'Hello. Testing email.';
'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.';
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 --email@example.com -t firstname.lastname@example.org
* Update the above paths, and the “from” (email@example.com) and “to” (firstname.lastname@example.org) email addresses. This email will only have a subject line, it will not have a body due to the limitations of the command line.
