[SOLVED] Failed AUTH: Must issue a STARTTLS command first

I cannot for the life of me figure out how to setup Bugzilla to send email using TLS. I got the Bugzilla site running, however, when I try to change my Bugzilla account email, the system fails with the following (I setup my email parameters to use my Amazon AWS email server):

An unexpected error occurred. This could be a temporary problem, or some code is behaving incorrectly. If this problem persists, please email this page to ...@.....com with details of what you were doing at the time this message appeared.

URL: http://example.com/userprefs.cgi?new_password1=&new_password2=&tab=account&old_login=jdoe%40example.com&realname=John%20Doe&new_login_name=johndoe422%40example.net&dosave=1&token=...&old_password=...

There was an error sending mail from 'bugzilla@example.com' to 'johndoe422@example.com': failed AUTH: Must issue a STARTTLS command first

Traceback:

at Bugzilla/Mailer.pm line 186.
Bugzilla::Mailer::MessageToMTA(...) called at Bugzilla/Token.pm line 116
Bugzilla::Token::IssueEmailChangeToken(...) called at /srv/www/bugzilla/userprefs.cgi line 120
main::SaveAccount(...) called at /srv/www/bugzilla/userprefs.cgi line 608

So I proceeded to try to fix this problem by following the instructions in: Bugzilla Alerts Using Gmail

I managed to install the Email::Send::SMTP::TLS module using cpanm (Not sure why I just cannot install any module via CPAN at all), after installation, the SMTP::TLS option does not appear in the drop-down. I just ignored it and continue to update Mailer.pm as instructed.

After that, when I refresh my bugzilla page, I get the following error:

Software error:

Global symbol "@args" requires explicit package name at Bugzilla/Mailer.pm line 138.

For help, please send mail to this site's webmaster, giving this error message and the time and date of the error.

I've read that perhaps it is because Email::Send::SMTP::TLS requires Net::SSLeay package. So I proceed to try to install it using cpanm. However, cpanm fails with the following log:

I do not know perl and cannot figure out why I'm getting errors left and right. I read in many places that I can simply install all available packages using command like:

/usr/bin/perl install-module.pl --all

However, this command does not work for me. (I can't install any modules using CPAN at all, not sure why) It pretty much just does nothing for me. This is the output I get when execute install-module.pl:

I'm not sure why things just don't work for me. Do I have a faulty perl installation or what? Can some perl guru please help?

Thanks!
