mailbox, yp,

[Michael Zeitlin]

      We have a problem with the mailbox tool working with a
      yellow pages domain whose server is a SUN running
      4.1.1 of SUNOS.

      When yp is turned off, the mailbox tool works great (of coarse
      no mail cancome in...)

      When yp is turned on...we get  mailbox: bad file number
      repeating a s a message and the icon is unresponsive...

      mail itself works ..( i can read an write mail without using
       the mailbox tool).

       any ideas on the source of the problems?
