configure Bugzilla with gmail smtp

This article explains how to use GMAIL SMTP(TLS AUTH) to send bugzilla alerts.
Bugzilla supports following methods to send mail alerts :

• sendmail
• SMTP

For SMTP method BugZilla uses Email::Send::SMTP Perl module. GMAIL SMTP uses TLS ( Transport Layer Security ) as authentication method, so Email::Send::SMTP can not be used for the same.
We need to use another perl module Email::Send::SMTP::TLS.
First step would be to install Email::Send::SMTP::TLS from CPAN. use following steps to do so :

• using CPAN SHELL
Lanch CPAN shell as follows

#cpan
capn>install Email::Send::SMTP::TLS
cpan shell might ask you to install additional modules, install them.

• compiling from source
Download source from HERE and execute following commands

1.tar zxvf Email-Send-SMTP-TLS-0.03.tar.gz
2.cd Email-Send-SMTP-TLS-0.03
3../configure
4.make
5.make install

Once Email:Send::SMTP::TLS is installed, BugZilla should have SMTP::TLS method to send alerts. This can be verified by logging in as admin to BugZilla and going to Administration -> Parameters -> Email

Now we need tweak BugZilla code. carefully execute following instructions and don't forget to backup files before you modify.
Go to your BugZilla installation directory and execute following command


1.cd Bugzilla

Open Mailer.pm file.
Search for following code( should be on line # 57)

1.sub MessageToMTA {

add following line after it


1.my ($smtp_server,$smtp_port);

search for following if block

1.if ($method eq "SMTP") {

and change it to

01.if ($method eq "SMTP" || $method eq "SMTP::TLS") {

02. ($smtp_server,$smtp_port) = split /:/,Bugzilla->params->{"smtpserver"};

03. push @args,

04. Host => $smtp_server,

05. User => Bugzilla->params->{"smtp_username"},

06. Password => Bugzilla->params->{"smtp_password"},

07. Hello => $hostname,

08. Debug => Bugzilla->params->{'smtp_debug'};

09. push @args, Port => $smtp_port if($smtp_port);

10. }

Now we need to do settings in bugzilla parameters.
Login as administrator to Bugzilla and go to Administration -> Parameters -> Email and do following settings
1. Select SMTP::TLS as mail_delivery_method

2. Enter your gmail address in mailfrom

3. Enter smtp.gmail.com:587 in smtpserver

4. Enter you@gmail.com in smtp_username

5. Enter gmail password in smtp_password

It will work pretty good.
