Hello, I installed qmail+mysql patch (from here: http://www.softagency.co.jp/mysql/qmail2.en.html) and everything was working fine. Today i was playing with maildrop and I don't know how that happend, but qmail is not working anymore with mysql authentication. Now it works with /etc/passwd ... The weird thing is that it is still querying the database and it gets the row with the user data (i checked the mysql.log) , but for some reason it then looks at /etc/passwd, does not finds the user and shows Sorry,_no_mailbox_here_by_that_name_(#5.1.1) ....... I checked everything, the permissions are ok, the control/sqlserver file has mysql_use yes attribute , check_host is set to "no" users exist in the database but why it then looks at /etc/passwd ? I only can mail to users in /etc/passwd now ... any ideas where to look for this problem? Also, if the user exists in /etc/passwd why doesn't it even look at mysql database? this was not exactly i was expecting installing this patch. Thanks for any help in advance nikolai
