Is it maybe the case to update the documentation, then? I can't find this
thing anywhere. Plus (from http://www.postfix.org/access.5.html):
*CASE FOLDING*
The search string is folded to lowercase before database
lookup. As of Postfix 2.3, the search string is not case
folded with database types such asregexp
<http://www.postfix.org/regexp_table.5.html>: orpcre
<http://www.postfix.org/pcre_table.5.html>: whose
lookup fields can match both upper and lower case.
There's no mention of special treatment for mail addresses as far as I
can see :(
Thanks for your help.
