At the following pasterbin: http://pastebin.com/ttQkZPvW you can find: a) 'postconf -m' output b) 'postconf -n' output c) cat /etc/postfix/check_recipient_access.regexp d) cat /etc/postfix/master.cf e) 'postmap -q' queries to /etc/postfix/check_recipient_access.regexp f) client telnet session to trigger the behaviour g) 'smtpd -v' maillog output In particular, g) gives evidence of case folding to lowercase while querying the regexp table, even with 'i' flag appended to the pattern. Postfix version: 2.6.6 Thanks, Fabio
