I would like to be able to run a SMTP server on port 25, but my ISP blocks it. Is there a way to use a different. I'm running XAMPP Mercury.

My ISP optimum online blocks port 25 and port 80 for regular users. They claim lots of viruses and malware are spread on these ports. Spreading propaganda IMO since 99% of websites run on port 80. Well I upgraded to Boost which lets me use those ports.
