After I upgraded to 7.4 today, I found many problems.
Firstly, I can login with the Web mail interface. I try to re-enable the webmail service in server-manager, then I can login with webmail interface.
But I found another problem, I can receive email but I cannot send email.
and here is the log message(qmail/current):
