In a nutshell, dropping the $ from next unless defined *{$Net::POP3::{$_}}{CODE};

To give next unless defined *{Net::POP3::{$_}}{CODE}; should work.

Though that would still issue a warning, so try:next unless defined *{"Net::POP3::$_"}{CODE};.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?

Thanks -- the suggestions helped get rid of the warning/error messages. However, there must be some other incompatibility since the code does not work as expected. I'll have to do what I was trying to avoid, viz., having to dig into the code to find out which pieces stop working in the new system. While doing this I'll also look to replacing the unmaintained CPAN modules with others such as NET::POP3_auth, Net::POP3::SSLWrapper, and NET::SMTP_auth.
