I wanted to make one which catches all external

I think |1[a-z\.]*\.org| should work, but I haven't tested it. The
phrase "1*" actaully means "zero or more occurrences of the character
1".
This should get it, I think.
$wgSpamRegex="/1.*\.org/";
Which is interpreted as
/1 - the literal characters "/" then "1" followed by
.* - a run of zero or more arbitrary characters
\. - the literal character "." (the backslash is needed to treat . as a
literal
rather than it's normal meaning of any character
org/ - the literal characters "org"
Thanks for replies.
In the end I modified Rotem's suggestion. I tested it using
http://ioctl.org/jan/test/regexp.htm and found that it matched with
the number "1" anywhere in the top level domain, not just at the start
hence:
|\.1[a-z\.]*\.org|
seems to cover it.
