Redirecting domains

[steakaphagus]

Hi, I have a number of domains (.co.uk, .info etc, about 10 in all) for my .com site. I've simply redirected all the domains to point to the .com one - is this OK as I've heard that search engines might see this unfavourably?
If it is a problem, what should I do to do this safely? Thanks

Check both non-www and www for each one. Check both the root and some internal page URLs. Make sure that they all issue a 301 redirect and that the redirect gets you to the final URL in just one step, not in a redirection chain.

technically it's better if you point all the domains to the one server and let that server handle the domain and url canonicalization rather than redirecting requests for each domain.
otherwise you could get the redirection chain for a non-canonical request as suggested by g1smd or a 301 followed by a 404 for an invalid request.
