Something like s/([._-])[0-9A-Fa-f]*([._-])/$1#$2/g (not tested, 
probably flawed, but you get the idea) ?

Why the '.' ? I don't see it in your examples.

The whitelists are your friends...

Given they all generate a per mail local-part, the from_awl won't be 
used. But the domain_awl will be.
Are SES and BATV popular ? on www.libsrs2.org, they don't have kind 
words for SES for example...

For SRS, I need to look more into it to tune proper regexps, meanwhile 
domain_awl should help.
