The error message above only occurs while trying to connect.

No connection can be established. There is no other way to interpret that error message. The error is provided by the native perl networking modules, not the UBB.

Only once the connection is established can any inspection of the SMTP transaction take place.

Have you tried configuring your UBB to use an external SMTP server? Have you tried making a UBB installation on another machine entirely and having it talk to the existing SMTP server? We need to establish if this is a problem with the SMTP server not accepting connections, or with the Perl installation not being able to create connections.
