ab at xxxx.com (/opt/rt3/lib/RT/Ticket_Overlay.pm:695)

In my RT_SiteConfig.pm, I have :
Set($MailCommand , 'sendmailpipe');
Set($SendmailArguments , "-t");
Set($SendmailPath , "/var/qmail/bin/sendmail");

I'm using Qmail. Also the watcher of my queues are not receiving replies or 
any email. Is there something particular to do for Qmail ?

Thanks for your help,
AB
