Sendmail, WAMP, and PHP Configuration for SMTP Email Delivery

In this issue, a user encountered difficulties while attempting to configure sendmail with their Gmail account on a WAMP server running on Windows 8.1. Sendmail is an SMTP email delivery agent used to handle email transmissions.

Problem Configuration:

The user faced errors when using port 465 for SMTP, resulting in a "Connection timed out" message. Additionally, port 587 exhibited a "Connection Closed Gracefully" message, despite no emails being sent.

Solution:

After troubleshooting various configurations, the user discovered that sendmail required administrator privileges to run. The steps involved in setting administrator permissions for sendmail.exe are as follows:

1. Right-click on sendmail.exe
2. Select "Properties"
3. Navigate to the "Compatibility" tab
4. Click on "Change settings for all users"
5. Check the box for "Run this program as Windows XP SP3 (Service Pack 3)"
6. Check the box for "Run this program as an administrator"

Verify Success:

Once administrator permissions were granted to sendmail.exe, both port 465 and 587 could be used successfully to send emails. The user's PHP code provided in the initial query demonstrated the successful sending of an email after the proper configuration.

Conclusion:

Granting administrator privileges to sendmail.exe proved to be a crucial step in resolving the email delivery issues. By following the steps outlined above, users can ensure that sendmail operates with the necessary permissions to handle SMTP email transmissions effectively within a WAMP environment.
