Connecting Testlink with Gmail SMTP - email

Question

so this is my first time asking here. I have been trying to enable any SMTP for my company's Testlink. However, I cant figure out why I cant manage to make it work since 8 hours ago. been spending my office hours trying to solve this problem and googling there and here but sadly, it seems like none of the solution works for me. if anyone could please kindly revise my code, I would be glad to have your kind help.
the error mostly about:
SMTP -> FROM SERVER:
SMTP -> FROM SERVER:
SMTP -> ERROR: EHLO not accepted from server:
SMTP -> FROM SERVER:
SMTP -> ERROR: HELO not accepted from server:
SMTP -> ERROR: AUTH not accepted from server:
SMTP -> NOTICE: EOF caught while checking if connectedSMTP Error: Could not authenticate. PROBLEMS SENDING MAIL TO: sapurabugzilla#gmail.com
Mailer Error: SMTP Error: Could not authenticate.
and most of the time it showed it cannot load TLS string.
here is my config.inc.php file :

Answer 1

change the following line in config.inc.php file
From :
$g_smtp_host = 'smtp.gmail.com:465';
To :
$g_smtp_host = 'smtp.gmail.com';
and try.
i had less stackoverflow reputation to comment your question so only posting it as answer.

Answer 2

Remove port from
$g_smtp_host = 'smtp.gmail.com:465';
like
$g_smtp_host = 'smtp.gmail.com';
and add port below as
$g_smtp_port = 465;
and select connection mode as ssl
$g_smtp_connection_mode = 'ssl';
