Hi,
I want to rewrite the username for authentication with managesieve.
If I authenticate with "\0original_username\0password", then everything
works fine, and perdition rewrites it to "\0rewritten_username\0password".
Unfortunatly some clients including squirrelmail/avelsieve and roundcube
send: "original_username\0original_username\0password", which gets
rewritten to:
"rewritten_username\0original_username\0password".
It looks like dovecot and cyrus only care for the username after the
first \0 which unfortunatly does not get rewritten via popmap.
