No, as far as I can tell its not even connecting to ryoko. Here is the debug information that Net::POP3 spits out:

Net::POP3: Net::POP3(2.21)
Net::POP3:   Net::Cmd(2.18)
Net::POP3:     Exporter
Net::POP3:   IO::Socket::INET
Net::POP3:     IO::Socket(1.1603)
Net::POP3:       IO::Handle(1.1505)

Thats as far as it gets before it hangs and times out. If I define the variable statically, here is what I get:

Net::POP3: Net::POP3(2.21)
Net::POP3:   Net::Cmd(2.18)
Net::POP3:     Exporter
Net::POP3:   IO::Socket::INET
Net::POP3:     IO::Socket(1.1603)
Net::POP3:       IO::Handle(1.1505)
Net::POP3=GLOB(0x830aac4)<<< +OK QPOP (version 3.1.2) at ryoko.leet.or
+g starting.

...and so on and so forth. I'm beginning to think this is some kind of bug in Net::POP3...
