; * QDMAIL is a program to scan the connected directory for various *
; * queued mail files and to print out the file type and *
; * destination host. It is adapted from MMAILR. *
; * *
; * MAILST is the server portion of the mail status program and runs*
; * in conjunction with MSTAT. See MSTAT.MAC for further description*
; * of mail status operating modes. MAILST is a modified version of *
; * QDMAIL. *
