Yes that looks quite good as a "be conservative in what you generate"
guideline. But some people take delight in including unusual characters
in mail addresses - if only because it confuses spam address harvesters.
Despite what that page says, most widely used MTAs do cope (I don't know
about widely used MUAs as I don't use Outlook :)). But as a data point,
I've certainly received and replied to mails with $ in the lefthandside.

srs may use =.
If somebody wants to write all mail to disk, not just their
locals, or a sub-set of locals(lists and dspam retrain aliases
from pop users), they'll need a better regex. Actually the
whole method may break because of file naming limitations.
Space chars will work for filenames.
Maybe it would be good to mime encode the whole string,
but then file wildcarding would only work on domain names.
That might be alright though.
