Is this is the context of header_filter_rules or something else? Also
what Mailman version?

Starting in 2.1.6, folded headers are unfolded by replacing the
new-line and following white space character with a single space which
"should" give "the correct thing" assuming the above for example is
new-line followed by tab followed by 'of'.

You could always use a pattern like


which will match whitespace, followed by 'out', followed by 1 or more
whitespace characters, followed by 'of', followed by some whitespace,
followed by 0 or one occurrences of 'the' and some whitespace,
followed by 'office' and whitespace.

See <http://docs.python.org/lib/re-syntax.html>.
