You should be using the Perl EXE file - the DLL is a bit unstable when used with UBB.classic.

Okay, so it seems that Perl is still being denied the ability to connect to the SMTP machine... Time to try from an outside source to be 110% sure. Do you have any other machines available to you (preferably a Unix-based machine as to also eliminate Windows from the problem list) that you can try a UBB install on?
