Qmail deferral...

[seiheng]

Hello to all,

I have encounter a following problem:

My qmail just gave a deferral message without explaining why the mail is
defer. Usaully, if there is any error occur, qmail will print out the
coz' of it. But this time it doesn't.

I like to know what kind of error that would possibly result in this
case.?

Thanks
