Could you be more specific: what exactly doesn't work anymore? Are there any error messages, timeouts, ...?
One quick way of testing whether your smtp server is still alive is to telnet to the server on port 25. It should respond with a more or less verbose greeting.

No error messages, no timeouts. Where as before I ran the script and within seconds an email appeared, now I run the script, it completes as before with no errors. But I receive no email. I can ping the smtp server, and I telnet'ed to it, as you suggested, all fine.

We're wandering away from Perl here, but nevertheless: you can check the mailqueue on the smtp server (if you have access to it) with the mailq command. It gives you a list of stuff that's waiting to be sent, with an explanation as to why it was not sent, if applicable.
If your mail does not show up, check the mailer logs (somewhere in /var/adm or /var/log, depending on your Unix version). If your mail does not show up there, it never got to the server.
If your mail server is on a Windows machine, people more knowledgeable about that than me will provide you with the equivalent commands and log files to check this (I hope ;) ).

A non-perl but valuable tool is the free ethereal protocol analyzer. It is multi-platform and has lots of features. Try watching the SMTP conversation -- that may lead you to the trouble. I find that using a protocol analyzer is often the quickest way to diagnose these things.
