IMHO http://www.vulnerabilities.org/analysis.html is a good alternative to securityspace. You can easily chose between a simple nmap scan or a nessus scan without registering or anything. As for checking that port 25 is listening on the firewall, the simplest thing is to telnet to port 25 of the firewall and see if it responds. This can easiest be done from a shell account on the internet, but also from the inside if your firewall rule includes the internal net as the source.

As an example, http://www.securityspace.com provides a number of auditing options, ranging from simple port scans, to full vulnerability assessments.
