• How to setup working SMTP in phpBB 3 with use GMail, PHP 5 and ISS 5

    Posted on November 3, 2013 by in MediaWiki

    Tested over

    • PHP 5.2.6
    • GMail
    • phpBB 3.0.1
    • ISS 5.1 (Windows XP)


    You was installed mySQL 5.x+, PHP 5.x+, phpBB 3.+, IIS 5.1. PHP 5.x+ could be installed from *.zip to i.e . ‘c:\php’ – it make less mess in operating system.

    You was configure PHP php-cgi.exe (not php5isapi.dll as ISAPI is not working with openssl!) on IIS.

    You was added to PATH variable path to PHP i.e. c:\php.

    You enable in php.ini php_openssl.dll.

    What to do

    Enter into phpBB following configuration:

    SMTP: Yes
    Mail Server: ssl://smtp.gmail.com
    Mail Server Port: 465
    Authorization method: LOGIN
    Login SMTP: your_name_of_account@gmail.com
    Password SMTP: your_password_of_account

    Common errors and problems

    PHP Log Contains: PHP Warning: PHP Startup: Unable to load dynamic library c:\php\ext\php_openssl.dll’ – The operating system cannot run %1.

    In majority of case you not:

    • use php-cgi.exe but use php5isapi.dll

        • if not add .php and reference c:\php\php-cgi.exe set limit to GET,HEAD,POST, set script engine, set check if that file exists.
        • if exists and is mapped to change as above
      • if .php was mapped to php5isapi.dll before change
        • back to ‘Start -> Administrative Tools -> Computer Management -> Internet Information Server -> Web Sites’
        • click right and select ‘Properties’
        • select tab ‘ISAPI Filters’
        • remove php5isapi.dll
