[rkaldung]

Environment

• OS: n.a.
• Browser: /bin/bash
• Znuny version: 6.3.1

Expected behaviour

Executing of bin/otrs.Console.pl without any errors

Actual behaviour

Executing of bin/otrs.Console.pl throws this error:

Error: Kernel::System::Console::Command::Dev::Tools::ImportFakeEmails could not be loaded: Can't locate Mail/IMAPClient.pm in @INC (you may need to install the Mail::IMAPClient module) (@INC contains: /opt/otrs/Custom /opt/otrs/Kernel/cpan-lib /opt/otrs /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /opt/otrs/Kernel/System/MailAccount/IMAP.pm line 17.
