You have to tweak the relay mailer args:

    define(`SMART_HOST', `windows.server')
    define(`RELAY_MAILER_ARGS', `TCP $h 2525')

If you are using a mailertable in Sendmail, please show us the
mailertable too.

This was copy/pasted all in one line, so I can't really tell which 'dnl'
applies to every line, or if none apply at all.
