Mail delivery problem

[Paul Tan]

Hi,

      I'm using Qmail+vpopmail+qmailadmin on linux server with reiserfs. My
problem is intermitten, local users can send mail to remote users without
problems, but occasionally they cannot send to other local users, there are
no error msgs but the postmaster gets all the mail ! I really do not know
what is going on.

      what other information do you guys need to solve this??

Thks a Million
