Hi It looks like lines in imapd.conf are limited to 4096 chars. Ho to setup thousand of admins or loginrealms options ? If it is not possible, what is the best way to patch cyrus: - increase buffer size in code reading imapd.conf - modify this code to support unlimited line length - make the code accept multiple 'admins' lines - add support for line continuation (ususaly \ at the end of the line) - add support for table lookup, in static file, in ldap or mysql Regards. -- Alain Spineux aspineux gmail com May the sources be with you ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
