When configuring Email on Bugzilla am getting the following error
All the required Perl Nodules and Net::SMTP::SSL are installed and up-to date.

perl 5, version 16, subversion 3 (v5.16.3)
Net::SMTP::SSL is up to date (1.04)

Any idea to resolve this?

Have you reviewed the troublshooting steps at the bugzilla documentation?
https://bugzilla.readthedocs.io/en/5...install-config

postfix, exim, or other MTA installed?
how does this host process mail outside of Bugzilla?

I have defined MTA mail server details on /etc/mail.rc and have tested with few mail services like mailx and mail. Am able to send email through these services.

But when I configure the same on Bugzialla and click on save button it give the error I have reinstalled the Net::SMTP::SSL and also verified my configuration with but nothing help me here.

What happened when you did that?

Those aren't "services" those are client programs/utilities.

/etc/mail.rc <--- sendmail or postfix?

2.2.3. checksetup.pl

"Next, rerun checksetup.pl. It reconfirms that all the modules are present, and notices the altered localconfig file, which it assumes you have edited to your satisfaction. It compiles the UI templates, connects to the database using the 'bugs' user you created and the password you defined, and creates the 'bugs' database and the tables therein."
says https://www.bugzilla.org/docs/2.20/h...iguration.html

How did you re-install those modules?
"Rerun the CPAN commands (or manual compile) using the full path to Perl from the top of checksetup.pl. This will make sure you are installing the modules in the right place." says this.

Your "goto" resource should should be https://www.bugzilla.org/docs/2.20/html/index.html
Bugzilla version?
OS version?
perl version?

You haven't provided much for us to go on.
Is this a new install of Bugzilla or an upgrade? Perhaps a clean start (do over) is necessary?

Nothing help me here either

"rerun checksetup.pl" is the only action I could find for you.
It likely won't "fix" it, but it may provide clues.
