1. I will first confirm that increasing the MCP-check timout fixes the
problem and lets mail from the 'slow' sites get through.

2. If increasing the timeout fixes the problem then I would like to know
why the MCP-checker is doing DNS lookups. Once I have permission I will
forward you a short message that can apparently reproduces this problem.

Will try to get back to you on these points ASAP.
