Trace enoughspace( ) Debug command-line switch
The MinFreeBlocks option (?§24.9.77 on page 1057) defines the minimum number of disk
blocks that must be reserved on the queue disk. If an incoming SMTP message will fill the
disk beyond this minimum, the message is rejected.
The -d4.80 debugging switch* traces the enoughspace( ) routine in conf.c. That routine
examines the disk space and prints the following if the MinFreeBlocks option (?§24.9.77 on
page 1057) was less than or equal to zero, or if the message??™s size is less than or equal to
zero:
enoughdiskspace: no threshold

Show failed mail Debug command-line switch
Mail can fail for a wide variety of reasons. The way that sendmail handles errors is determined
by the setting of the ErrorMode option (?§24.9.47 on page 1028) in the configuration
file. The -d6.1 (a.k.a. -d6) debugging switchcauses sendmail to print the error-handling
mode that is in effect at the time it first begins to handle failed mail:
savemail, errorMode = char, id = qid, ExitStat = errornum
e_from= ?†? output of printaddr( ) here (?§15.3 on page 533)
Here, char is either p for print errors; m for mail-back errors; w for write-back errors; e for
special Berknet processing; or q for ???don??™t print anything??? (all of which are described under
the ErrorMode option in ?§24.9.47 on page 1028).
